Frequently Asked Questions - OfficeConnect Remote 812 3COM

How do I set up the OfficeConnect Remote 812 for the first time?

First, check the package contents. Connect the DSL cable to the ADSL port and the phone jack, connect the power adapter, and connect a workstation to one of the LAN ports using the supplied Ethernet cable. Then, select a boot mode via the DIP switches on the back panel. For most users, set DIP switches to 'off, on, off, off' for DHCP Smart Mode. Insert the Installation CD and follow the on-screen instructions. The web-based Remote 812 Manager will guide you through configuration.

What are the boot mode options and how do I select them?

The router has three boot modes controlled by DIP switches 1-4 (off=down, on=up):
DHCP Smart Mode (switches: off, on, off, off) – assigns LAN IP 192.168.200.254 and acts as DHCP server.
Default Bridge Mode (off, off, on, off for VPI=0 VCI=35; or off, off, off, on for VPI=8 VCI=35) – works as a bridge with preconfigured VPI/VCI.
Unconfigured Mode (all off) – all parameters must be set manually. These modes only take effect on a factory-reset unit.

How do I reset the router to factory defaults?

Unplug the power cable, set the DIP switches to the desired boot mode, then plug the power cable back in while pressing the Reset button on the back panel for about five seconds. This erases all previous configuration and applies the new boot mode.

How can I test if my Internet connection is working?

Use the Ping tool from the Remote 812 Manager: go to Tools > Ping and enter the ISP's gateway IP. Also, from a workstation, open a command prompt and type 'ping '. A successful reply indicates connectivity. Additionally, try browsing to a known website like http://www.3com.com. If pages load, configuration is correct.

What do the LEDs on the front panel mean?

Power: solid green when powered on.
Alert: flashing during initialization.
ADSL: off – no signal; green – link up; blinking green – data transfer; orange – synchronizing with CO equipment.
LAN (Ports 1-4): on when a client is connected, blinking with activity. If an LED is off when it should be on, check cable connections and power.

How do I configure my workstation to use DHCP Smart Mode?

Set your workstation to obtain an IP address automatically. In Windows, go to Control Panel > Network > TCP/IP properties, select 'Obtain an IP address automatically' and remove any default gateway or DNS entries. The router’s DHCP server will assign an IP in the 192.168.200.0/24 range. Reboot the workstation after changes.

Can I use the router as a simple bridge without any configuration?

Yes. Set the DIP switches to Default Bridge Mode (off, off, on, off for VPI=0 VCI=35). The router will bridge all traffic with RFC 1483 encapsulation. Ensure the VPI/VCI matches your ISP’s values. No further setup is needed; you will be connected immediately after power-on.

How do I change the default administrative password?

After logging into the Remote 812 Manager with the default credentials (username: root, password: !root), go to Configuration > Administrator Login. Delete the default profile and create a new one with a secure username and password (max 32 characters for username, 15 for password). Remember to save your changes.

What should I do if the ADSL LED is off?

First, ensure the DSL cable is securely connected to both the router’s ADSL port and the telephone wall jack. Check the cable for damage. If the cable is okay, contact your Internet Service Provider to verify that ADSL service is active and that the line is properly provisioned. You can continue configuring the router even with the ADSL LED off.

Where can I find the full user manual and software updates?

The full Online User’s Guide and CLI Guide are on the Installation CD in PDF format. Software updates and additional documentation are available on the 3Com website at http://www.3com.com/. The Instant Update utility on the CD can check for new firmware automatically.

What Can the OfficeConnect Remote 812 do?

The Remote 812 is a stand-alone BRouter with data interfaces to a Local Area Network (LAN) and a Wide Area Network (WAN).

Below is a representation of how your Remote 812 connects a LAN and WAN.

graph TD
    A["Local LAN"] --> B["HTML Management"]
    B --> C["OfficeConnect Remote ADSL Router"]
    C --> D["ATM"]
    D --> E["Edge Router"]
    E --> F["Internet"]
    D --> G["Edge Router"]
    G --> H["Remote Office"]

The Remote 812 contains one ADSL WAN interface port. It also provides support for ATM.

The Remote 812 supports Point-to-Point Protocol (PPP) and RFC 1483 over the WAN interface. The LAN interface is a four-port Ethernet 10Base-T hub.

The Remote 812 allows one or more networked workstations to connect to other computers on a remote LAN and can also provide high-speed access to the Internet. The Remote 812 provides static and dynamic routing of the Internet Protocol (IP) and Internetwork Packet Exchange (IPX) protocols as well as bridging, with support for learning bridge and 802.1d spanning tree functionality to eliminate loops. Other important features include: Routing Information Protocol (RIP), Simple Network Management Protocol (SNMP), address translation, telnet, and packet filtering. It can also provide DHCP services for your LAN, including automatic assignment of IP addresses to workstations.

The web browser-based Remote 812 Manager and the IP Wizard provide a user-friendly configuration interface.

OfficeConnect Remote 812 Boot Mode Options

To simplify the installation process, the Remote 812 can be initialized with pre-configured parameters using the DIP switches located on the back of the unit. There are three Boot Mode options:

■ DHCP Smart Mode
■ Default Bridge Mode
■ Unconfigured Mode

It is important to note that these boot modes only take effect if the unit has not been previously configured. To erase the existing configuration, reference Appendix A.

The DIP switch settings and the corresponding Boot Mode option are as follows:

Table 1-1 DIP Switch Settings

1 2 3 4 Mode

off on off off DHCP Smart Mode

off off on off Default Bridge Mode, VPI=0, VCI=35

off off off on Default Bridge Mode, VPI=8, VCI=35

off off off off Unconfigured Mode

Option One: DHCP Smart Mode

You can use the DHCP Smart Mode if:

■ You plan on using private addresses on the LAN (i.e. your Service Provider has provided you with only 1 public IP address),
■ You plan on using the Remote 812's DHCP Server
The Remote 812 will power up with the following “DHCP Smart Mode” configuration:
■ LAN IP address = 192.168.200.254, Netmask 255.255.255.0.
■ DHCP IP address pool (40 addresses): 192.168.200.1-40
■ DNS name: ocrdsl-3com.com.

■ Administrative Login profile, User Name: root and Password:!root

Option Two: Default Bridge Mode

Use this mode if you want the Remote 812 to function as a bridge automatically, with no special configuration. You will not be required to use the Setup Wizard or install any software from the CD unless you want to change the configuration or if you would like to use Instant Update in the event a software update to your Remote 812 is posted on 3Com's web site (you can install from the CD at any time).

Verify the VPI/VCI settings in the table above match values your Service Provider has given you. The Remote 812 will power up with the following configuration:

■ Bridge network on the LAN Interface
■ A remote site profile named "bridge" is set up to bridge all traffic with RFC 1483 encapsulation on the specified VPI/VCI.
■ Spanning Tree Disabled
■ Administrative Login profile: User Name: root and Password:!root

Option Three: Unconfigured Mode

Set all switches to OFF to boot your unit in Unconfigured Mode. You must set all of the configuration parameters. This allows you complete flexibility with your configuration.

INSTALLING THE OFFICE CONNECT REMOTE 812 ADSL ROUTER

Introduction

In this release of the OfficeConnect Remote 812, we have provided an Installation Map and Install CD to assist in your setting up your unit and getting started. This chapter provides more information on the process for your assistance:

■ OfficeConnect Remote 812 Hardware Installation
■ Hardware Configuration
■ LED Light Operation
■ Workstation Configuration (and selecting a Mode)
■ Remote 812 Software Installation
■ Changing the Login Name and Password
■ Starting the Remote 812 Manager
■ Configuring the Remote 812

OfficeConnect Remote 812 Hardware Installation

This section provides a quick hardware setup procedure for the Remote 812. Follow the steps below to learn more about setting up your router:

Back Panel Features

Below is a representation of the back panel. Familiarizing yourself with the connections will help in properly setting up your Remote 812.

■ Console Port — You should not need to use the Console Port unless you are setting up in Unconfigured Mode and thus need to use the Command Line Interface (CLI) to configure your router. The DB-9 terminal port connects the Remote 812 with your console. Then you would use a terminal emulator program to access CLI and run Quick Setup and QuickVC. The Installation Map gives instructions.
- Reset button — This button resets the configuration of the router. See Appendix B for more information about resetting your router's configuration with the reset button.
■ DIP (Dual Inline Package) Switches (4) — Switches 1 through 4 can be turned on and off in certain combinations for different configurations. See the section titled “OfficeConnect Remote 812 Boot Options” in Chapter 1 for complete instructions on which switches to set for which options.
■ Power Inlet — The power port attaches to an external, 15-volt DC power supply included in your package. The other end of the power supply cable connects to a standard electrical socket.
- Ethernet (LAN) Ports (4) — The shielded, 8-pin, RJ45 Ethernet (10Base-T) ports connect the Remote 812 with the LAN. A 10Base-T cable is supplied in the package to make this connection.
■ MDI/X Switch — Swaps the transmit (Tx) and receive (Rx) signal pairs on Ethernet port 1. When MDI/X is “out” (not depressed), Port 1 is pinned the same as the remaining 3 ports. In this mode, a workstation’s Ethernet port or the cascade port on another hub can be connected to any of the four ports on the unit. When MDI/X is pressed “in,” then Port 1 on the unit becomes a cascade hub port, for connection to a non-cascade port on another hub. The MDI/X button must be “out” to use Port 1 for connection to a workstation.
■ ADSL Modem Port — An RJ11 line port connects your Remote 812 to the telephone company wall jack. An RJ11 modem cable is provided.

■ Stacking Clip—A stacking clip is provided which will allow you to stack your OfficeConnect Remote 812 with other 3Com equipment if necessary.

Hardware Configuration

1 Select a Boot Option — The Remote 812 has three boot options. These are controlled by the settings of the 4 DIP (Dual Inline Package) switches on the back of the unit. Boot options only affect the operation of a unit which does not presently have any configuration settings (i.e., the unit is new, the Configuration reset button has been pressed, or a delete configuration command has been executed from the CLI or Remote 812 Manager interface). See the section about DIP switch settings in Chapter 1, "Getting Started".

2 Connect the DSL Modem Line — Use the modem cable provided to connect the Remote 812 ADSL port to telephone company wall jack.

3 Connect the Power — Connect the power plug to the back of the unit. Make sure the power plug is connected securely to the Remote 812. Then, plug the unit into an electrical outlet.

4 Connect to a Local LAN (select one of below)

■ Connect directly to a workstation — Connect the 10Base-T cable into any LAN port. The MDI/X button must be out to use the LAN port furthest to the right(Port 1) to connect to a workstation. Up to four workstations can be directly connected to the Remote 812.
■ Connect to an Ethernet Hub — Press the MDI/X button on the back panel so it is in the “in” position and plug the 10Base-T cable into the right-hand LAN port (Port 1).

5 Connect the Console Cable (optional) — If Windows is your operating system, you will not need to connect the console cable because you will use the Remote 812 Manager to configure your unit. The Remote 812 Manager uses a web browser instead of a Command Line Interface (CLI). If your operating system is MAC or Unix, you will be

using CLI. Locate the serial cable included in your package. Connect one end of the cable to the DB-9 console port on the Remote 812 and plug the other end into a serial port on your workstation.

The Remote 812 Hardware Installation is now complete. Continue with the next section to verify your Remote 812 is operating correctly.

LED Light Operation

After you boot up, the LEDs indicate whether the Remote 812 is working properly and when certain features are in use. There are four sets of LEDs on the Remote 812. They operate as shown in the following table:

Table 2-1 LED Operation

LED Group LED Indicator Status Operation
Alert Flashing Software is initializing.
Power Power ON Power is on.
ADSL Link Status	ADSL connection	OFF	No signal has been detected.*
		Green	Link is up.
		Blinking Green	Link is up, data transfer is occurring.
		Orange	The unit is attempting to achieve synchronization with the CO equipment.
LAN Status (Ports 1-4)	Client Connection	ON A client is connected to the corresponding port on the hub.

If an LED is not operating properly, consult the OfficeConnect Remote 812 Online User's Guide and refer to the section on Troubleshooting.

* If the ADSL LED is off, there may be a problem with the ADSL cable or line. However, you can continue setting up your Remote 812 even if the ADSL Link Status LED is off.

Workstation Configuration

The IP configuration on your Workstations must correspond with the Remote 812 configuration. The

following sections detail your options given the Boot Mode you have selected.

Workstation Configuration Using DHCP Smart Mode

If you have chosen to utilize DHCP Smart Mode, you will need to configure some parameters on your workstation.

For DHCP Smart Mode, you must set up all workstations on the Remote 812's LAN to automatically obtain their IP address. This is the default setting in Windows 95.

If you have configured IP addresses manually on your workstation, verify that the IP address is on the 192.168.200.0 Class C subnet and that the default router is 192.168.200.254.

Note: Refer to Appendix B for instructions on how to change or verify that your workstation is configured for automatic assignment of an IP address and corresponding parameters.

After you have configured your workstation, proceed to the next section, "Software Installation".

Workstation Configuration Using the Default Bridge Mode

When the Remote 812 is configured as a bridge, refer to your Service Provider's instructions on how to set up your workstation. Proceed to Chapter 3, "Testing the Configuration".

Workstation Configuration Using the Unconfigured Mode

When the Remote 812 is not configured with an IP address on the LAN, you must use the IP Wizard program, which is included on your CD, or connect to the console port to configure an IP address before you can access the unit with a Web Browser.

Proceed to the next section, Office Connect 812 Software Installation, for instructions on installing the CD. Then, if you are using Windows, refer to the subsequent section, Assigning an IP Address with the IP Wizard. The IP Wizard will detect your Remote 812 on the LAN and then prompt you to specify the IP address you want to configure it with.

If you are using MAC or Unix, you will need to use the console port and a terminal emulator program to access CLI, using the settings: 9600 Bits per Second, 8 Data Bits, No Parity, Flow control equal to Xon/Xoff. Refer to the CLI Users Guide (which is a .pdf file on the Install CD) for a description of the commands to use.

OfficeConnect Remote 812 Software Installation

The Remote 812 Install CD contains the Online Guides, the IP Wizard Utility, and the 3Com Instant Update software.

The IP Wizard and Instant Update are available at this time only for Windows users. If you are a Windows user and are doing a normal install, your install CD should be automatically copying the basic files you need to complete your installation at this point. The CD also contains Microsoft Internet Explorer 4, and Adobe Acrobat Reader 3.01.

If you are a MAC or Unix-based user, copy or refer to the CLI Users Guide for instructions on using the CLI and the "Quick Setup" and "QuickVC" programs to complete your installation.

If you do not have at least Microsoft Internet Explorer 3.02 or Netscape Navigator 3.0, you should install the Microsoft Internet Explorer 4 included on this CD in order to use the web-based OfficeConnect Remote 812 Manager for configuring your Remote 812. You must also have Adobe Acrobat Reader installed to view the PDF formatted CLI Guide included on this CD.

If you are not installing the Remote 812 at this time but you want to copy the information and help files, you may do so from the Install CD Main Menu:

The Remote 812 is shipped with its operational software pre-installed in the unit's FLASH memory. A copy of the operational software is also provided on the CD.

The Remote 812 operational software (the *.nac file) included on the CD is copied to your hard drive and not the Remote 812 unit. Unless you specify otherwise, it is

installed to the default location:

C:\Program Files\3Com\ocr812\1\_0\Update

If you need to reload the software on your unit, please refer to the OfficeConnect Remote 812 ADSL Router Online User's Guide (on your installation CD).

If you need to install Microsoft Internet Explorer 4, launch the installation by putting the Remote 812 Installation CD in your CD-ROM drive and selecting "Install Internet Explorer 4" from the menu.
If you need to install the Adobe Acrobat Reader to view your printable files, launch the installation by putting the Remote 812 Installation CD in your CD-ROM drive and selecting "Install Adobe Acrobat 3.01" from the menu.
- You may optionally choose to install the 3Com Instant Update utility. Launch the installation by putting the Remote 812 Installation CD in your CD-ROM drive and selecting “Install 3Com Instant Update” from the menu.

Instant Update periodically checks the 3Com web site for a new release of the Remote 812 code. When a new release of the code is found, Instant Update copies it to your workstation. You will then need to install the code onto your Remote 812 unit. This procedure is explained in the OfficeConnect Remote 812 ADSL Router Online User's Guide (on your Installation CD).

Configuring the OfficeConnect Remote 812 Manager

Configuring in Bridge Only Mode

If you selected Bridge Only Mode as your Boot Option, no further action is needed. You should be connected to your ISP or remote office. If you can't access the remote site, examine the DIP switch settings on your unit. To reset to a different Boot Mode, change the DIP switch settings and then hold the reset button (on the back of the router) in for five seconds while powering on the router.

If you selected DHCP Smart Mode or Unconfigured Mode, your Remote 812 must be assigned an IP address in order for your web browser to communicate with it. You must also have an administrative login profile (user name and password) assigned.

If you assign the IP address with DHCP Smart Mode or with the IP Wizard, the administrative login name is root and the password is !root. After you access the unit with your web browser, you are strongly advised to delete this login profile and create a new one with a secure name and password. (Maximum character length of login name = 32, password maximum character length = 15.)

Configuring in DHCP Smart Mode

In Windows, the browser will automatically launch at the conclusion of your automated installation procedure and you will have the assistance of the IP Wizard. In MAC or Unix, you must manually start the browser.

Proceed to the section: Getting Started with the OfficeConnect Remote 812 Manager

Configuring in Unconfigured Mode

Windows Users: Windows users will have the assistance of the IP Wizard, as in DHCP Smart Mode.

You will need to input a static address that agrees with other addresses on your LAN.

The IP Wizard: IP Wizard will search the LAN for all unconfigured Remote 812s. As each unconfigured unit is found, the unit's MAC address is placed in the selection box. For multiple Remote 812s, you can determine which MAC address belongs to the one you want to configure by disconnecting the Remote 812's Ethernet cable and running IP Wizard again. The missing MAC Address belongs to that Remote 812. If the IP Wizard does not find any unconfigured units, and you are sure your unit is unconfigured, refer to the chapter on Troubleshooting in the OfficeConnect Remote 812 ADSL Router Online User's Guide.

Select which Remote 812 you want to configure and enter its LAN IP address and netmask; then press Set.

Proceed to the next section.

MAC and Unix Users: MAC and Unix users (and those configured in Bridge Only Mode but with alternate VPI/VCI settings) will be using Command Line Interface (CLI).

Connect the console cable provided with the Remote 812 kit to the router and a Com port on your workstation.

Use a terminal emulator program to access the Command Line Interface, using the following settings:

Then run Quick Setup and then QuickVC.

Getting Started with the OfficeConnect Remote 812 Manager

1 When your web browser opens up, to get to the Remote 812 "home page," either enter the unit's LAN IP address or, if DHCP Smart Mode is in use, the DNS host name (ocrdsl-3com.com) into the Location or Address field of your web browser. Notice that typing the http://is optional (for example, you can type simply 192.168.200.254).

2 The web browser will then prompt you to log in.

Enter the administrative login name and password (default login name root and Password !root).

After successful authentication, you will be presented with the Remote 812 "Wizard page."

If you do not see this screen, refer to the section on Troubleshooting in the Online User's Guide (install from your CD).

Configuration Using the Remote Site Wizard

When you first connect to the Remote 812 Manager and a VC profile has not yet been configured, you will be automatically directed to the Remote Site Wizard page shown below. This page prompts the User for the bare minimum information it takes to set up a Remote Site profile to your ISP. Once the Remote Site has been configured, the user will be directed to the Remote 812 Home Page, where he or she will have access to a more advanced feature set.

A description of each field follows. After you have entered in your configuration, when you want to send down the configuration to the Remote 812, press the "configure" button. You will then be redirected to the OfficeConnect Remote 812 Home page. If you do not want to configure the Remote Site profile, press the "cancel" button and you will be redirected to the OfficeConnect Remote 812 Home page. If you want to access additional features not provided to you when using the Remote Site Wizard, access the Remote Site profile from the Home page by selecting Configuration, then Remote Sites.

Remote Site IP Wizard field descriptions

Remote Site Name

The Remote Site Name is used to identify the profile and it's associated parameters. The name can be up to 32 characters and typically describes the remote site you are connected to, such as my_isp or my_corp.

Network Service

Your Service provider should provide you with the type of Network Service to configure for your WAN connection. The Remote 812 supports the following Network Services:

• PPP – The Point to Point Protocol is a WAN interface protocol between the Remote 812 and your ISP's Remote Server. The protocol provides built in negotiation for addresses and connection parameters, and can route multiple protocols over a single link.
  ■ RFC 1483 – Is a defined protocol standard that describes two encapsulation methods for carrying network traffic over ATM AAL5. The encapsulation methods; routed and bridged, must be configured the same on both ends of the link. To select routed encapsulation, select RFC 1483. To select bridged encapsulation, select RFC 1483 with MAC encapsulation.
  ■ RFC 1483 with MAC encapsulation – specifies RFC 1483 with a bridge encapsulation. This feature enables the Remote 812 to function as a router but to work in a

bridged environment. When enabled, the network level addresses are used for forwarding, but the MAC layer addresses are pre-pended in the ethernet header over the Wide Area Connection.

ATM VC Parameters

Your Service provider should provide you with the Virtual Path Identifier (VPI) and Virtual Connection Identifier (VCI) values to configure for your connection. These are pre-assigned virtual path information used to route ATM cells through the network to your ISP.

Network Address Translation

This feature enables many workstations on the LAN to share a single public address when accessing information over a public network (Internet). Enable this feature if you have a Single User Account with your ISP and disable it if you have been provided public IP addresses to use on the LAN.

WAN IP Information

Your Service provider will provide you with the public IP address(es) to use on your WAN Interface or on the LAN.

If you have selected PPP as your Network Service, the WAN IP addresses will be dynamically learned from the Remote PPP Server. The Remote 812 will not prompt you for WAN IP Information if PPP has been selected.

If you have selected RFC 1483 and have enabled Network Address Translation (NAT), you will be prompted for the WAN interface Address. This is the single public address that will be shared by all privately addressed clients on your LAN when they access the public network. You will also be prompted for a corresponding netmask, which will default to a class C (255.255.255.0) value.

If you have selected RFC 1483 and have not enabled NAT, you can configure a WAN Interface address or a Remote Subnet address and corresponding netmask.

When selecting RFC 1483 with MAC encapsulation, you must specify the Remote Gateway Address. If you have

enabled NAT, you will also be prompted for the WAN interface. If you did not enable NAT, the WAN interface address is optional. If you do not configure the WAN Interface address, the Remote 812 LAN ethernet address should be a public address.

■ Advanced Troubleshooting

General Testing

After configuring the OfficeConnect Remote 812 for remote site connection(s), follow these steps to test the connections.

Step 1: Check Interface Status

1 Be sure the DSL cable is connected to the OfficeConnect Remote 812 and the phone jack, and then check the ADSL Status LED on the front of the unit. It should be green or blinking green.

2 If the unit is not in a location where you can see the LEDs, go to the OfficeConnect Remote 812 Manager home page. Select Monitor > Interface Status. The following table should display:

Interface Status
Name	Oper Status	Admin Status
loopback	UP	UP
eth:1	UP	UP
atm:1	UP	UP

Ensure that Oper Status of interface atm:1 is UP.

If the status of atm:1 is not UP, check the cable connection to make sure it is securely plugged into the unit and check

the cable to make sure it is not damaged. If there are no apparent cable problems, contact your service provider.

Step 2: Check Network Status

Check that all LAN and WAN networks are up. From the OfficeConnect Remote 812 Manager "home page," select Monitor > Networks > Network Status. You should see one active network for each of the LAN protocols configured (IP, IPX, and/or Bridge).

You should also see an active network for each of the protocols configured over each remote site. For example, if you have a remote site profile for Internet access, you should see a corresponding IP network in the table. If you are connected to a remote office, with IP routing, you should see corresponding networks for this, too.

Below is an example wherein an IP network is configured over the LAN (indicated by eth:1), and the remote site "red" is configured for IP over the WAN (indicated by atm:1).

Name	Prot	Int	State	Type	Network Address
ip	IP	eth:1	ENABLED	STATIC	192.168.200.254/C
red-ip-I4	IP	atm:1	ENABLED	DYNAMIC	10.0.0.254/H

If you don't see the expected networks, there is probably a remote site profile configuration error. You should check the following in the Configuration > Remote Site (WAN) screens.

■ Is the remote site enabled?
■ Is the protocol (IP) enabled?
■ Are the network addresses correct?
■ Is the Network Service (PPP or RFC 1483) correct?
■ Is the remote site profile ATM information (VPI / VCI) correct?

If necessary, contact your ISP or remote site administrator to confirm the information provided to you. When all

problems are resolved, continue to the IP testing section below.

IP Testing

Run a PING to make sure the OfficeConnect Remote 812 can reach the remote router. You can PING by using the OfficeConnect Remote 812 Manager, from MS-DOS, or test the connection through your Internet Service Provider.

PINGing from the OfficeConnect Remote 812 Manager will test the connection from the OfficeConnect Remote 812 to the network.

The DOS PING will check the connection from your PC through the OfficeConnect Remote 812 ADSL Router to the network.

You can also test the connection using your Internet Browser, if you have Internet access.

Option 1: OfficeConnect Remote 812 Manager Ping to ISP or Remote Site Network

Open the OfficeConnect Remote 812 Manager, select

Tools > Ping. Enter the address you wish to ping, whether it is the ISP or a remote site. Press the Submit button.

A Ping Response screen will appear, with the response from the ping. The following responses may occur.

Ping Responses

is alive

The PING was successful.

If a name was entered in the Ping page input field, the corresponding IP address is displayed on the Response page.

PING: no route to host

A valid IP address or name was entered but the routing table does not indicate how to reach the network that the IP address belongs to.

PING: host unreachable

This means that the IP address is currently unreachable. This is indicative of a network problem. The router sent the message either to the specific network to which the IP address belongs or to a default gateway. If it was sent to the specific network and the network was learned via RIP, there is probably a temporary network problem. If the network is a static entry in the routing table, it may have been entered incorrectly.

PING: timeout waiting for reply from .

The host network is probably reachable but there is no answer from this IP Address. There are a couple of possible explanations for this: The IP Address might not be assigned to any unit; the path from the OfficeConnect Remote 812 to the unit is so slow that the PING response did not get back in the allotted time frame; or there may be a temporary break in the path.

DNS Errors

Network Name: could not be resolved. Network Name: could not be resolved due to a problem interacting with the Name Server.

The name could not be resolved. Either no DNS server was located or the server(s) did not have the name in the host table list. This error will also appear if the user entered an invalid IP address such 10.100.100.256.

Network Name: could not be resolved due to a timeout on the request.

No response was received from the DNS server to which the DNS request was sent. This could be due to a network connection problem or Internet congestion.

Option 2: DOS Ping to ISP or Remote Site Network

1 From the a workstation on the local LAN, get to an MS-DOS prompt and type ping where the remote IP address is the address of a host on the remote network (Ex: ping 10.0.0.12). If no

address was provided, contact the ISP or the remote site administrator for an IP address to ping.

2 The OfficeConnect Remote 812 will send the PING request. A reply from 10.0.0.12 indicates success.

An example script of a failed ping is:

C:\ping 10.0.0.12

Pinging 10.0.0.12 with 32 bytes of data:

Request timed out.

Request timed out.

Request timed out.

Request timed out.

An example script of a successful ping is:

C:\ping 10.0.0.12

Pinging 10.0.0.12 with 32 bytes of data:

Reply from 10.0.0.12 bytes=32 time=140ms TTL=240

Reply from 10.0.0.12 bytes=32 time=147ms TTL=240

Reply from 10.0.0.12 bytes=32 time=140ms TTL=240

Reply from 10.0.0.12 bytes=32 time=135ms TTL=240

C:_

It is not unusual for the first few attempts to time out. If you don't receive a response the first time, try PINGing the router again. If you still don't receive a response, the most likely cause is incorrect routing entries.

Option 3: Internet Browser (Internet Access Only)

If you are connecting to the Internet, start a web browser and enter an address, such as http://www.3com.com. If the 3com web site home page comes up, all is configured correctly and you are on your way!

If the 3Com web site home page does not appear, the problem may be incorrect DNS server addresses on your workstation. To investigate other possible problems, refer to the section on Troubleshooting in the OfficeConnect Remote 812 ADSL Router Online User's Guide.

Advanced Troubleshooting

For more detailed troubleshooting information, refer to Troubleshooting in the OfficeConnect Remote 812 ADSL Router Online User's Guide (on your Installation CD).
