Congratulations on your purchase of the ADSL2 Barricade™ g, hereafter referred to as the "Barricade". We are proud to provide you with a powerful yet simple communication device for connecting your local area network (LAN) to the Internet. For those who want to surf the Internet in the most secure way, the Barricade provides a convenient and powerful solution.

About the Barricade

The Barricade provides Internet access to multiple users by sharing a single-user account. Support is provided for both wired and wireless devices. New technology provides wireless security via Wired Equivalent Privacy (WEP) encryption and MAC address filtering. It is simple to configure and can be up and running in minutes.

Features and Benefits

Built-in ADSL2/2+ modem - supports download speeds up to 24Mbps
- Local network connection via four 10/100 Mbps Ethernet ports
Built-in IEEE802.11g 54Mbps Wireless Access Point (AP)
- DHCP for dynamic IP configuration, and DNS for domain name mapping

• Firewall with Stateful Packet Inspection, client privileges, intrusion detection, and NAT
• NAT also enables multi-user Internet access via a single user account, and virtual server functionality (providing protected access to Internet services such as web, FTP, e-mail, and Telnet)
  VLAN and QoS (Quality of Service) support
• User-definable application sensing tunnel supports applications requiring multiple connections
• Easy setup through a web browser on any operating system that supports TCP/IP

Applications

Many advanced networking features are provided by the Barricade:

- Wireless and Wired LAN

The Barricade provides connectivity to 10/100 Mbps devices, and wireless IEEE 802.11g compatible devices, making it easy to create a network in small offices or homes.

- Internet Access

This device supports Internet access through an ADSL connection. Since many DSL providers use PPPoE or PPPoA to establish communications with end users, the Barricade includes built-in clients for these protocols, eliminating the need to install these services on your computer.

- Shared IP Address

The Barricade provides Internet access for up to 253 users via a single shared IP address. Using only one ISP account, multiple users on your network can browse the web at the same time.

Virtual Server

If you have a fixed IP address, you can set the Barricade to act as a virtual host for network address translation. Remote users access various services at your site using a constant IP address. Then, depending on the requested service (or port number), the Barricade can route the request to the appropriate server (at another internal IP address). This secures your network from direct attack by hackers, and provides more flexible management by allowing you to change internal IP addresses without affecting outside access to your network.

- DMZ Host Support

Allows a networked computer to be fully exposed to the Internet. This function is used when NAT and firewall security prevent an Internet application from functioning correctly.

Security

The Barricade supports security features that deny Internet access to specified users, or filter all requests for specific services that the administrator does not want to serve. The Barricade's firewall also blocks common hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding. WEP (Wired Equivalent Privacy), SSID Broadcast disable, and MAC filtering provide security over the wireless network.

Before installing the ADSL2 Barricade™ g, verify that you have all the items listed under the Package Contents list. Also be sure that you have all the necessary cabling before installing the Barricade. After installing the Barricade, refer to "Configuring the ADSL Router" on page 4-1.

Hardware Description

The Barricade contains an integrated ADSL modem and connects to the Internet or to a remote site using its RJ-45 WAN port. It can be connected directly to your PC or to a local area network using any of the four Fast Ethernet LAN ports.

Access speed to the Internet depends on your service type. Full-rate ADSL provides up to 8 Mbps downstream and 1 Mbps upstream. G.lite (or splitterless) ADSL provides up to 1.5 Mbps downstream and 512 kbps upstream. ADSL2+ provides up to 24Mbps downstream and 1Mbps upstream. However, you should note that the actual rate provided by specific service providers may vary dramatically from these upper limits.

Data passing between devices connected to your local area network can run at up to 100 Mbps over the Fast Ethernet ports and 54 Mbps over the built-in wireless access point.

The Barricade includes an LED display on the top for system power and port indications that simplifies installation and network troubleshooting.

It also provides the following ports on the rear panel:

Parameter	Description
LAN IP
IP Address	The IP address of the Barricade.
IP Subnet Mask	The subnet mask of the network.
DHCP Server	Enable or Disable the DHCP server function. By default the DHCP server is enabled for automatic IP address assignment to client devices.
VLAN Binding
LAN1 to LAN4	Select VLAN group for the corresponding LAN port. By default all ports members of the Default VLAN.
Lease Time	Set the IP lease time. For home networks this may be set to Forever, which means there is no time limit on the IP address lease.
IP Address Pool
Start IP Address	Specify the start IP address of the DHCP pool. Do not include the ip address of the Barricade in the client address pool. If you change the pool range, make sure the first three octets match the gateway's IP address, i.e., 192.168.2.xxx.
End IP Address	Specify the end IP address of the DHCP pool.
Domain Name	If your network uses a domain name, enter it here. Otherwise, leave this field blank.

VLAN

VLANs are organized and controlled by VLAN Profiles. Up to 4 VLAN profiles can be created. Once a VLAN profile is created, you should add interfaces into the VLAN by changing the VLAN setting of that interface. Please note that only those interfaces of IEEE 802 bridging type (ex. LAN ports and 1483 Bridging PVCs) can be added to a VLAN.

Click Add VLAN to setup the profile.

VLAN Profile

Enter parameters of the profile to define a VLAN.

Description: enter a name or description for the VLAN.
IP Address: enter the IP address.
- Subnet Mask: enter the subnet mask.
- NAT Domain: select private or public.
- IGMP Snooping: Internet Group Management Protocol (IGMP) snooping is a method by which Layer 2 devices can "listen in" on IGMP conversations between hosts and routers. When a switch hears a group join message from a host, it notes which switch interface it heard the message on, and adds that interface to the group. Similarly, when a Layer 2 switch hears a group leave message or a response timer expires, the switch will remove that host's switch interface from the group.
- IGMP Querier: if the IGMP Querier is enabled, then the router will periodically query all multicast group members on the specified VLAN.

WIRELESS

The Barricade also operates as a wireless access point, allowing wireless computers to communicate with each other. To configure this function, all you need to do is enable the wireless function, define the radio channel, the SSID, and the security options. Check Enable and click SAVE

SETTING.

Channel and SSID

You must specify a common radio channel and SSID (Service Set ID) to be used by the Barricade and all of its wireless clients. Be sure you configure all of its clients to the same values.

Parameter	Description
SSID	Service Set ID (SSID) is the name given to the wireless network. TheSSID must be the same on the Barricade and all of its wireless clients.
SSID Broadcast	Enable or disable the broadcasting of theSSID. Disabling broadcasting of theSSID provides added security by hiding your wireless network.
Wireless Mode	This device supports both 11g and 11b wireless networks. Make your selection depending on the type of wireless network that you have.
Channel	The radio channel used by the wireless router and its clients to communicate with each other. This channel must be the same on the Barricade and all of its wireless clients.
	The Barricade will automatically assign itself a radio channel, or you may select one manually.

Access Control

Using the Access Control functionality, you can restrict access based on MAC address. Each PC has a unique identifier known as a Medium Access Control (MAC) address. With MAC filtering enabled, the computers whose MAC address you have listed in the filtering table will be able to connect (or will be denied access) to the Barricade.

• Enable MAC Filtering: select to turn on/off this feature.
• Access Rule for registered MAC address: select to allow/deny access for the registered MAC addresses. Selecting Allow means only MAC addresses registered here will be able to connect to the router. Selecting Deny means only the MAC addresses registered here will be denied access to the router.
• MAC Address Filtering List: you can use the drop-down menu to select and quickly copy the entry to the MAC Filtering table.

Security

To make your wireless network safe, you should turn on the security function. The Barricade supports WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected) and WPA2 security mechanisms.

Three options are available:

No WEP, No WPA
WEP only
WPA only

WEP

If you want to use WEP to protect your wireless network, you need to set the same parameters for the Barricade and all your wireless clients.

Parameter	Description
WEP Mode	Select 64 bit or 128 bit key to use for encryption.
Key Entry Method	Select Hex or ASCII to use for encryption key
Key Provisioning	Select Static if there is only one fixed key for encryption. If you want to select Dynamic, you would need to enable 802.1X function first.

You can automatically generate encryption keys using the passphrase or manually enter the keys. To generate the keys automatically enter a passphrase and click GENERATE. Select the default key from the drop-down menu and click SAVE SETTINGS.

Note: Before saving settings the key is shown in clear text. If you wireless client does not have a passphrase utility make a note of the default

key before saving settings. This is so you can configure your wireless client with the correct key.

To manually configure the encryption key, enter five hexadecimal pairs of digits for each 64-bit key, or enter 13 pairs for the single 128-bit key.

(A hexadecimal digit is a number or letter in the range 0-9 or A-F)

Note that WEP protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet.

Note: The passphrase can consist of up to 32 alphanumeric characters.

WPA

Wi-Fi Protected Access (WPA) combines temporal key integrity protocol (TKIP) and 802.1X mechanisms. It provides dynamic key encryption and 802.1X authentication service. The Barricade supports both WPA and WPA2.

Parameter	Description
WPA mode	Select WPA or WPA2 or mixed mode.
Cypher suite	The security mechanism used in WPA for encryption.
Authentication	Choose 802.1X or Pre-shared Key to use as the authentication method.
	•802.1X: for the enterprise network with a RADIUS server.
	•Pre-shared key: for the SOHO network environment without an authentication server.
Pre-shared key type	Select the key type to be used in the Pre-shared Key.
Pre-shared Key	Type in the key here.
Group Key	The period of renewing broadcast/multicast key.
Re_Keying

802.1X

If 802.1X is used in your network, then you should enable this function for the Barricade.

Parameter	Description
802.1XAuthentication	Enable or disable this authentication function.
Session Idle timeout	Defines a maximum period of time for which the connection is maintained during inactivity.
Re-AuthenticationPeriod	Defines a maximum period of time for which the authentication server will dynamically re-assign a session key to a connected client.
Quiet Period	Defines a maximum period of time for which the Barricade will wait between failed authentications.
Server Type	Select RADIUS as the authentication server.
RADIUS Server Parameters
Server IP	The IP address of your authentication server.
Server Port	The port used for the authentication service.
Secret Key	The secret key shared between the authentication server and its clients.
NAS-ID	Defines the request identifier of the Network Access Server.

WDS

The Wireless Distribution System (WDS) provides a means to extend the range of a Wireless Local Area Network (WLAN). WDS allows an Access Point (AP) to establish a direct link to other APs and to allow stations to roam freely within the area covered by the WDS.

To refresh the list of available access points, Click Rescan.

Available access points will show up on the AP MAC Address Table, check the box to add that particular access point to the WDS.

Advanced Setting

To change the settings on this screen is recommended for experienced user only. It is advised to leave the parameters at the default value.

• Beacon Interval: this represents the amount of time between beacon transmissions. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point).

• DTIM Interval: Delivery Traffic Indication Message, indicates when the DTIM occurs. A DTIM interval is a count of the number of beacon frames that must occur before the access point sends the buffered multicast frames. For example, a DTIM interval of one means that the multicast frames are sent after each beacon frame. A DTIM interval of two indicates that multicast frames are sent after every two beacon frames, and so on. Because each beacon frame includes a field that identifies the DTIM interval, all stations know when to wake up and receive multicast frames if they're implementing power saving.

• Fragmentation Threshold: this is the maximum size for directed data packets transmitted. Larger frames fragment into several packets this size or smaller before transmission. The receiving station then reassembles the transmitted fragments.

• RTS Threshold: RTS stands for "Request to Send". This parameter controls what size data packet the low level RF protocol issues to an RTS packet. Using a small value causes RTS packets to be sent more often, consuming more of the available bandwidth, therefore reducing the apparent throughput of the network packet. However, the more RTS packets that are sent, the quicker the system can recover from interference or collisions.
  CTS Protection Mode: CTS stands for "Clear to Send". If this value is set to Auto. The AP will automatically use CTS Protection Mode when the 802.11g products are experiencing severe problems and are not able to transmit to the AP in an environment with heavy 802.11b traffic. This function boosts the AP's ability to catch all 802.11g transmissions but will decrease the performance.
• WMM Mode: Wireless Multimedia support. WMM prioritizes traffic according to 4 AC (Access Categories) - voice, video, best effort, and background. However, it does not provide guaranteed throughput. It is suitable for simple applications that require QoS, such as Wi-Fi Voice over IP (VoIP) phone.

NAT

Network Address Translation allows multiple users to access the Internet sharing one public IP.

Address Mapping

Allows one or more public IP addresses to be shared by multiple internal users. This also hides the internal network for increased privacy and security. Enter the Public IP address you wish to share into the Global IP field. Enter a range of internal IPs that will share the global IP into the "from" field.

Virtual Server

If you configure the Barricade as a virtual server, remote users accessing services such as web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the Barricade redirects the external service request to the appropriate server (located at another internal IP address).

For example, if you set Type/Public Port to TCP/80 (HTT or web) and the Private IP/Port to 192.168.2.2/80, then all HTTP requests from outside users will be transferred to 192.168.2.2 on port 80. Therefore, by just entering the IP address provided by the ISP, Internet users can access the service they need at the local address to which you redirect them.

The more common TCP service ports include:
HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110.

A list of ports is maintained at the following link: http://www.iana.org/assignments/port-numbers.

Special Application

Some applications require multiple connections, such as Internet gaming, video-conferencing, and Internet telephony. These applications may not work when Network Address Translation (NAT) is enabled. If you need to run applications that require multiple connections, use these screens to specify the additional public ports to be opened for each application.

NAT Mapping Table

This screen displays the current NAPT (Network Address Port Translation) address mappings.

ROUTING

These screens define routing related parameters, including static routes and RIP (Routing Information Protocol) parameters.

Static Route

Parameter	Description
Index	Check the box of the route you wish to delete or modify.
Network Address	Enter the IP address of the remote computer for which to set a static route.
Subnet Mask	Enter the subnet mask of the remote network for which to set a static route.
Gateway	Enter the WAN IP address of the gateway to the remote network.

Click Add to add a new static route to the list, or check the box of an already entered route and click Modify. Clicking Delete will remove an entry from the list.

RIP

RIP sends routing-update messages at regular intervals and when the network topology changes. When a router receives a routing update that includes changes to an entry, it updates its routing table to reflect the new route. RIP routers maintain only the best route to a destination. After updating its routing table, the router immediately begins transmitting routing updates to inform other network routers of the change.

Parameter	Description
General RIP Parameters
RIP mode	Globally enables or disables RIP.
Auto summary	If Auto summary is disabled, then RIP packets will include sub-network information from all sub-networks connected to the router. If enabled, this sub-network information will be summarized to one piece of information covering all sub-networks.
Table of current Interface RIP parameter
Interface	The WAN interface to be configured.
Operation Mode	Disable: RIP disabled on this interface. Enable: RIP enabled on this interface. Silent: Listens for route broadcasts and updates its route table. It does not participate in sending route broadcasts.
Version	Sets the RIP (Routing Information Protocol) version to use on this interface.
Poison Reverse	A method for preventing loops that would cause endless retransmission of data traffic.
Authentication Required	None: No authentication. Password: A password authentication key is included in the packet. If this does not match what is expected, the packet will be discarded. This method provides very little security as it is possible to learn the authentication key by watching RIP packets. MD5: An algorithm that is used to verify data integrity through the creation of a 128-bit message digest from data input (which may be a message of any length) that is claimed to be as unique to that specific data as a fingerprint is to a specific individual.
Authentication Code	Password or MD5 Authentication key.

Routing Table

Parameter Description

Flags	Indicates the route status: C = Direct connection on the same subnet. S = Static route. R = RIP (Routing Information Protocol) assigned route. I = ICMP (Internet Control Message Protocol) Redirect route.
Network Address	Destination IP address.
Netmask	The subnetwork associated with the destination. This is a template that identifies the address bits in the destination address used for routing to specific subnets. Each bit that corresponds to a “1” is part of the subnet mask number; each bit that corresponds to “0” is part of the host number.
Gateway	The IP address of the router at the next hop to which frames are forwarded.
Interface	The local interface through which the next hop of this route is reached.
Metric	When a router receives a routing update that contains a new or changed destination network entry, the router adds 1 to the metric value indicated in the update and enters the network in the routing table.

FIREWALL

The Barricade Router's firewall inspects packets at the application layer, maintains TCP and UDP session information including time-outs and the number of active sessions, and provides the ability to detect and prevent certain types of network attacks.

Network attacks that deny access to a network device are called Denial-of-Service (DoS) attacks. DoS attacks are aimed at devices and networks with a connection to the Internet. Their goal is not to steal information, but to disable a device or network so users no longer have access to network resources.

The Barricade protects against the following DoS attacks: IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding. (For details see page 4-61.)

The firewall does not significantly affect system performance, so we advise leaving it enabled to protect your network. Select Enable and click the SAVE SETTINGS button to open the Firewall submenus.

Access Control

Access Control allows users to define the outgoing traffic permitted or not-permitted through the WAN interface. The default is to permit all outgoing traffic.

Parameter	Description
Enable Filtering Function	Click Yes to turn on the filtering function.
Normal Filtering Table	Displays a summary of the filtering rules configured.

To add the PC to the filtering table:

1. Click Add PC on the Access Control screen.
2. Define the appropriate settings for client PC services.
3. Click OK and then click SAVE SETTINGS to save your settings.

MAC Filter

The Barricade can also limit the access of hosts within the local area network (LAN). The MAC Filtering Table allows the Barricade to enter up to 32 MAC addresses that are not allowed access to the WAN port. Please note that this filter only applies to ethernet clients.

Click Yes to enable, or No to disable this function.

Enter the MAC address in the space provided.

URL Blocking

The Barricade allows the user to block access to web sites by entering either a full URL address or just a keyword. This feature can be used to protect children from accessing violent or pornographic web sites.

You can define up to 30 sites here.

Schedule Rule

You may filter Internet access for local clients based on rules. Each access control rule may be activated at a scheduled time. Define the schedule on the Schedule Rule screen, and apply the rule on the Access Control screen.

Follow these steps to add a schedule rule:

1. Click Add Schedule Rule on the Schedule Rule screen.
2. Define the appropriate settings for a schedule rule.

Click OK and then click SAVE SETTINGS to save your settings.

Intrusion Detection

Intrusion Detection Feature

Stateful Packet Inspection (SPI) and Anti-DoS firewall protection (Default:Enabled) — The Intrusion Detection Feature of the Barricade Router limits access for incoming traffic at the WAN port. When the SPI feature is turned on, all incoming packets will be blocked except for those types marked in the Stateful Packet Inspection section.

RIP Defect (Default: Enabled) — If an RIP request packet is not acknowledged to by the router, it will stay in the input queue and not be released. Accumulated packets could cause the input queue to fill, causing severe problems for all protocols. Enabling this feature prevents the packets from accumulating.

Discard Ping to WAN (Default: Disabled) — Prevent a ping on the Barricade's WAN port from being routed to the network.

Scroll down to view more information.

Stateful Packet Inspection

This is called a "stateful" packet inspection because it examines the contents of the packet to determine the state of the communications; i.e., it ensures that the stated destination computer has previously requested the current communication. This is a way of ensuring that all communications are initiated by the recipient computer and are taking place only with sources that are known and trusted from previous interactions. In addition to being more rigorous in their inspection of packets, stateful inspection firewalls also close off ports until connection to the specific port is requested.

When particular types of traffic are checked, only the particular type of traffic initiated from the internal LAN will be allowed. For example, if the user only checks "FTP Service" in the Stateful Packet Inspection section, all incoming traffic will be blocked except for FTP connections initiated from the local LAN.

Stateful Packet Inspection allows you to select different application types that are using dynamic port numbers. If you wish to use the Stateful Packet Inspection (SPI) to block packets, click on the Yes radio button in the "Enable SPI and Anti-DoS firewall protection" field and then check the inspection type that you need, such as Packet Fragmentation, TCP Connection, UDP Session, FTP Service, H.323 Service, or TFTP Service.

Note: The firewall does not significantly affect system performance, so we advise enabling the prevention features, and leaving them at the default settings to protect your network.

DMZ

If you have a client PC that cannot run an Internet application properly from behind the firewall, you can open the client up to unrestricted two-way Internet access. Enter the IP address of a DMZ (Demilitarized Zone) host on this screen. Adding a client to the DMZ may expose your local network to a variety of security risks, so only use this option as a last resort.

SNMP

Use the SNMP configuration screen to display and modify parameters for the Simple Network Management Protocol (SNMP).

Community

A computer attached to the network, called a Network Management Station (NMS), can be used to access this information. Access rights to the agent are controlled by community strings. To communicate with the Barricade, the NMS must first submit a valid community string for authentication.

Note: Up to five community names may be entered.

Trap

Specify the IP address of the NMS to notify when a significant event is detected by the agent. When a trap condition occurs, the SNMP agent sends an SNMP trap message to any NMS specified as a trap receiver.

Parameter Description

IP Address	Traps are sent to this address when errors or specific events occur on the network.
Community	A community string (password) specified for trap management. Enter a word, something other than public or private, to prevent unauthorized individuals from accessing information on your system.
Version	Sets the trap status to disabled, or enabled with V1 or V2c. The v2c protocol was proposed in late 1995 and includes enhancements to v1 that are universally accepted. These include a get-bulk command to reduce network management traffic when retrieving a sequence of MIB variables, and a more elaborate set of error codes for improved reporting to a Network Management Station.

UPNP

The Universal Plug and Play architecture offers pervasive peer-to-peer network connectivity of PCs of all form factors, intelligent appliances, and wireless devices. UPnP enables seamless proximity network in addition to control and data transfer among networked devices in the office, home and everywhere within your network.

UPnP allows the device to automatically:

• join a network
• obtain an IP address
• convey its capabilities and learn about the presence and capabilities of other devices.

Check the Enable radio button to activate the function.

QOS

The QoS (Quality of Service) function allows you to differentiate traffic types and provide high-priority forwarding service for applications such as VoIP or gaming.

Parameter	Description
Enable or disable QoS module function	Check to enable or disable this function.
Diffserv Forwarding Groups
BE	Best Effort forwarding, set the percentage for this type od Qos.
AF1x	Set the percentage for four different types of Assured Forwarding.
AF2x
AF3x
AF4x
EF	Expedited Forwarding, is intended to provide low delay, low jitter and low loss delivery of packets.

Traffic Mapping

Use this screen to classify traffic into Diffserv forwarding groups and outgoing VCs.

Click Add traffic class to add traffic class.

Traffic Statistics

This screen shows the WAN outbound traffic statistics of all the Diffserv forwarding groups in the last 12 hours.

Click Refresh to renew the list.

ADSL

ADSL (Asymmetric Digital Subscriber Line) is designed to deliver more bandwidth downstream (from the central office to the customer site) than upstream. This section is used to configure the ADSL operation type and shows the ADSL status.

ADSL Parameters

This screen allows you to specify the ADSL standards to operate with. You may explicitly set a specific standard, or choose "Automatic" to automatically negotiate with remote DSLAM.

ADSL Status

The Status screen displays information on connection line status, data rate, operation data and defect indication, and statistics.

Parameter	Description
Status
Line Status	Shows the current status of the ADSL line connection.
Link Type	Shows the type of link.
Data Rate
Upstream	Maximum upstream data rate.
Downstream	Maximum downstream data rate.
Operation Data/Defect Indication
Noise Margin	Maximum upstream and downstream noise margin.
Attenuation	Maximum reduction in the strength of the upstream and downstream signal.
Fast Path FEC Correction	There are two latency paths that may be used: fast and interleaved. For either path, a forward error correction (FEC) scheme is employed to ensure higher data integrity. For maximum noise immunity, an interleaver may be used to supplement FEC.
Interleaved Path FEC Correction	An interleaver is basically a buffer used to introduce a delay, allowing for additional error correction techniques to handle noise. Interleaving slows the data flow and may not be optimal for real-time signals such as video transmission.
Fast Path CRC Error	The number of Fast Path Cyclic Redundancy Check errors.
Interleaved Path CRC Error	The number of Interleaved Path Cyclic Redundancy Check errors.
Loss of Signal Defect	Momentary signal discontinuities.
Fast Path HEC Error	Fast Path Header Error Concealment errors.
Interleaved Path HEC Error	Interleaved Path Header Error Concealment errors.
Statistics
Received Cells	Number of cells received.
Transmitted Cells	Number of cells transmitted.

DDNS

Dynamic Domain Name Service (DDNS) provides users on the Internet with a method to tie their domain name to a computer or server. DDNS allows your domain name to follow your IP address automatically by having your DNS records changed when your IP address changes.

This DDNS feature is powered by:

DynDNS.org
TZO.com
NO-IP.com

With a DDNS connection you can host your own web site, email server, FTP site, and more at your own location even if you have a dynamic IP address.

TOOLS

Use the Tools menu to backup the current configuration, restore a previously saved configuration, restore factory settings, update firmware, and reset the Barricade.

Ping Utility

This tool allows you to test network connection status. You can specify a domain name or a valid IP address of the remote host for ping test.

Enter the destination domain name or the IP address in the Destination Address field, and click Execute.

Trace Route Utility

Traceroute is the program that shows you the route over the network between two systems, listing all the intermediate routers that a connection must pass through to get to its destination. It can help you determine why your connections to a given server might be poor, and can often help you figure out where exactly the problem is. It also shows you how systems are connected to each other.

Enter the domain name or IP address in the IP Address or Domain Name field, and click Traceroute.

The Router keeps a log of the traceroute test, click Clear Log to delete the records.

Configuration Tools

• Backup allows you to save the Barricade's configuration to a file.
• Restore can be used to restore the previously saved backup configuration file.
• Restore to Factory Defaults resets the Barricade back to the original settings.

Troubleshooting Chart
Symptom	Action
LED Indicators
Power LED is Off	·Check connections between the Barricade, the external power supply, and the wall outlet. ·If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or external power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses, or surges at the power outlet. If you still cannot isolate the problem, then the external power supply may be defective. In this case, contact Technical Support for assistance.
Link LED is Off	·Verify that the Barricade and attached device are powered on. ·Be sure the cable is plugged into both the Barricade and the corresponding device. ·Verify that the proper cable type is used and that its length does not exceed the specified limits. ·Be sure that the network interface on the attached device is configured for the proper communication speed and duplex mode. ·Check the adapter on the attached device and cable connections for possible defects. Replace any defective adapter or cable if necessary.
Network Connection Problems
Cannot ping the Barricade from the attached LAN	·Verify that the IP addresses are properly configured. For most applications, you should use the Barricade's DHCP function to dynamically assign IP addresses to hosts on the attached LAN. However, if you manually configure IP addresses on the LAN, verify that the same network address (network component of the IP address) and subnet mask are used for both the Barricade and any attached LAN devices. ·Be sure the device you want to ping (or from which you are pinging) has been configured for TCP/IP.
Management Problems
Cannot connect using the web browser	• Be sure to have configured the Barricade with a valid IP address, subnet mask, and default gateway. • Check that you have a valid network connection to the Barricade and that the port you are using has not been disabled. • Check the network cabling between the management station and the Barricade.
Forgot or lost the password	• Press the Reset button on the rear panel (holding it down for at least five seconds) to restore the factory defaults.
Wireless Problems
A wireless PC cannot associate with the Barricade.	·Make sure the wireless PC has the same SSID settings as the Barricade. See “Channel and SSID” on page 4-35. ·You need to have the same security settings on the clients and the Barricade. See “Security” on page 4-37.
The wireless network is often interrupted.	·Move your wireless PC closer to the Barricade to find a better signal. If the signal is still weak, change the angle of the antenna. ·There may be interference, possibly caused by a microwave ovens or wireless phones. Change the location of the interference sources or of the Barricade. ·Change the wireless channel on the Barricade. See “Channel and SSID” on page 4-35. ·Check that the antenna, connectors, and cabling are firmly connected.
The Barricade cannot be detected by a wireless client.	·The distance between the Barricade and wireless PC is too great. ·Make sure the wireless PC has the same SSID and security settings as the Barricade. See Barricade. See “Channel and SSID” on page 4-35 and “Security” on page 4-37.

Ethernet Cable

Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

Specifications

Cable Types and Specifications
Cable	Type	Max. Length	Connector
10BASE-T	Cat. 3, 4, 5 100-ohm UTP	100 m (328 ft)	RJ-45
100BASE-TX	Cat. 5 100-ohm UTP	100 m (328 ft)	RJ-45

Wiring Conventions

For Ethernet connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be red and the other, red with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.

Each wire pair must be attached to the RJ-45 connectors in a specific orientation. The following figure illustrates how the pins on an Ethernet RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.
