Error! Reference source not found. Features

Once configured, the Error! Reference source not found. is able to use your modem(s) to connect to your ISP (Internet Service Provider). The Error! Reference source not found. will provide the log-in information required by the ISP. You

can seamlessly connect to the Internet as if you had a permanent connection. This sophisticated, yet easy-to-use device incorporates the following features.

• Dial-On-Demand. A connection is established to the Internet as required.
• User-Configurable Bandwidth Utilization. When using multiple modems or ISDN TAs, users can choose between “Time Saving Mode” (use all bandwidth) or “Money Saving Mode” (maximize bandwidth utilization).
• Inactivity Time Out. The modem will be disconnected if no line activity is detected. The time-out period ("Idle Time") is user-adjustable.
• PPP Authentication. This is used to validate the log-on to your Internet Service Provider.
• DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request.
  The Error! Reference source not found. can act as a DHCP Server.
• Easy Setup. Either a communications program and direct cable connection; or a WEB browser, can be used.
• Configuration Security Features. Optional password protection is provided to prevent unauthorized users from modifying the configuration.
• Hassle-free LAN Installation. An auto-sensing LAN connection eliminates the need for configuration during installation in a 10Base2/10BaseT network.

• Multi Segment LAN Support. If you have a Router, PCs on other LAN segments can use the Error! Reference source not found. to access the Internet.

• Remote Management. The Error! Reference source not found. can be managed from a workstation anywhere on the LAN, using a WEB browser.

• E-Mail Gateway. The Error! Reference source not found. can act as a Gateway for incoming E-Mail, allowing LAN users to share E-Mail accounts. Up to 4 accounts and 50 users are supported.
• Firewall Protection. All incoming data packets are monitored and all incoming server requests are filtered, thus protecting your network from malicious attacks from external sources.

Firewall Protection

The firewall protection provided by the Error! Reference source not found. is an intrinsic side effect of IP sharing. All users on the LAN share a single external IP address. From the external viewpoint, there is no network, only a single device.

For internal users, the Error! Reference source not found. acts as a “transparent proxy server”, translating the multiple internal IP addresses into a single external IP address.

For external requests, any attempt to connect to local resources are blocked. The Error! Reference source not found. will not “reverse translate” from a global IP address to a local IP address.

This type of “natural” firewall provides an impregnable barrier against malicious attacks.

Package Contents

The following items should be included:

• The Error! Reference source not found.
- Power Adapter
• Serial Cable (for configuration ONLY)
• This User's Manual

If any of the above items are damaged or missing, please contact your dealer as soon as possible.

Meta Password

Please remove the Sensitive Information page at the front of this manual and store it in safe place. It contains the important Meta Password which can be used if the regular password is lost or forgotten. (Note: This Meta Password can only be used with the Terminal Configuration mode.)

2 Installation

Requirements

• Ethernet Network employing 10BaseT or 10Base2 cable and the TCP/IP protocol.
  • An external modem or ISDN TA (Terminal Adapter).
• Configuration serial cable for Terminal mode configuration (supplied).
  • Single user account with a local ISP.

Procedure

The installation choices are as follows.

Configure, then Install

Configuration is done using a serial cable connection and a VT100 terminal compatible program, before installation. The only advantage of this method is that you can change the default IP Address (192.168.0.1) before connection to your LAN.

Install, then Configure

Here, you connect the Error! Reference source not found. to your network and then configure it using your WEB Browser. If the default IP Address (192.168.0.1) is already used by another device, the other device must be turned OFF until the

Error! Reference source not found. is allocated a new IP Address during configuration.

LAN Installation

Installing your new Error! Reference source not found. in your existing Ethernet LAN is quick and easy. Simply follow the instructions below:

1. Choose an Installation Site

Select a place on the network to install the Error! Reference source not found.. Remember that you need phone jacks and power outlets near your chosen location.

2. Connect Network Cable

The Error! Reference source not found. supports two types of network cables: Thin Ethernet (10Base2, BNC connector) and Twisted Pair Ethernet (10BaseT, RJ-45 connector). During power up, the unit automatically detects the type of network cable and adjusts to that environment.

10Base2 Cabling:

If your network uses 10Base2 cable, insert a BNC “T” connector into the Error! Reference source not found.’s BNC port. Connect the cable to one end of the “T” connector and connect the outgoing cable to the other end. If the Error! Reference source not found. is at the end of the network, then cap off the other end of “T” connector with a 50-ohm terminator. Also, keep in mind that the maximum effective length between the ends of a 10Base2 network is 185 meters.

10BaseT Cabling:

If your network uses 10BaseT cable, insert one end into the Error! Reference source not found.'s RJ-45 jack and the other end into the 10BaseT hub. Keep in mind that the maximum effective length from the hub to the device is 100 meters.

Warning: Do not attempt to connect more than one type of cable at the same time or change the network cable while the Error! Reference source not found. is powered On.

3. Connect Modem & Phone Line

Connect the modem, using a standard serial cable, to the Error! Reference source not found.'s serial port. Next, connect a telephone line from an RJ-11 style phone jack to the modem.

4. Connect Power Adapter

Connect the modem's power adapter to the modem and the Error! Reference source not found.'s power adapter to the Error! Reference source not found.. Power both devices On.

Only use the power adapter provided with your unit. Using a different one may cause hardware damage.

5. Check the LEDs

When the Error! Reference source not found. is powered On, both LEDs should light, then the Error LED should go off. If the Error LED stays on, there is a hard-

ware problem. For more information on the LEDs, refer to the LED Status table in Chapter 1.

This page was deliberately left blank.

• IP Address
• Default Gateway Address
  • DNS (Domain Name Server) Address

The correct settings will depend upon whether or not you have enabled the DHCP server in the Error! Reference source not found..

If DHCP is Enabled

IP Address

If the DHCP function in the Error! Reference source not found. is enabled, then your PCs should be set to obtain an IP address automatically. In Windows 95, this is done by setting the Properties for the TCP/IP protocol. This proce-

dure is described in the following section. For operating systems other than Win 95, check your system documentation.

1. Select the Control Panel - Network option on the Start Menu. You should see a screen like the one following.

Figure 14: Network Configuration

1. Select the TCP/IP protocol for your network card. Then click on the Properties button. You should then see a screen like the following.

Figure 15: IP Address (Win 95)

1. Click on the radio button to obtain an IP address automatically, as shown above.

Default Gateway Address

This should be left blank. The DHCP server will provide this information.

DNS (Domain Name Server)

This should be “Enabled” but the fields can be left blank. The DHCP server will provide this information also.

If DHCP is Disabled

IP Address

Each workstation must have a unique IP address. There should be no need to change any existing addresses.

Default Gateway Address

This value will depend on whether or not you have a router installed on your LAN.

NO Router

Set the Default Gateway Address to the IP address (Device IP Address) assigned to the Error! Reference source not found. during configuration.

Router

Leave this at the current setting (the address of the router).

DNS (Domain Name Server)

Enter the DNS address provided or recommended by your ISP. This is the same value that was entered into the DNS IP Address field in the Error! Reference source not found. during configuration.

Router Address Configuration

If you have a router, you must enter the IP Address (Device IP Address) of the Error! Reference source not found. as the Default Gateway in the router. Check the documentation for your router to see how this is done.

If your LAN contains multiple routers, ask your LAN administrator to perform the necessary router configuration.

It is essential that the router pass all IP packets for devices not on the local LAN to the Error! Reference source not found., so that they can be forwarded to the Internet.

Internet Access

No action is required to gain Internet access. Simply use your Browser as if you had a permanent connection.

If no connection currently exists, there will be a short delay while the modem connects to your ISP.

E-Mail Configuration

IF you are using the Error! Reference source not found. to share E-Mail accounts, then each user sharing an account must configure their E-Mail program with the following data.

Name	The User ID entered in the E-MailUser Screen of the Error! Reference source not found.. Note the following limitations on User Ids:Multiple words are NOT allowedPunctuation and special characters should NOT be used.User Ids are case insensitive.
E-Mail Address	The full name of the E-Mail account which is being shared, as provided by your ISP.e.g. [e-mail]
SMTP Server(Outgoing Mail)	The SMTP Server address as provided by your ISP
POP3 Server(Incoming Mail)	Set this to the IP Address of the Error! Reference source not found.
POP3 Account	The User ID entered in the E-MailUser Screen of the Error! Reference source not found..
Password	The user password entered in the E-Mail User screen of the Error! Reference source not found..

• Note that outgoing E-mail is sent normally; only incoming E-mail is processed by the Error! Reference source not found..
• If you find that some of your incoming E-mail does not include your name, and is therefore considered "Unrouted Mail", ask those senders to record your E-Mail Address in the following format.

"user_id"mail95account@mail95address

- Your printed E-Mail Address (e.g. on your business card) should also show your E-Mail address in the format above.

Sharing E-Mail Example

Say your name was B. Jones, the Error! Reference source not found. uses its default IP Address (192.168.0.1) and the other information was as follows:

E-Mail Addressas provided by your ISP	[e-mail]
SMTP Serveras provided by your ISP	smpt09.com
POP3 Serveras provided by your ISP	ms02.com
POP3 Account Nameas provided by your ISP	greatco
POP3 Account passwordas provided by your ISP	9087654

To share this E Mail Account, the entries on the following page would have to be made. Your E-Mail Address would become:

"bjones"[e-mail]

Error! Reference source not found. "Mail Account"

Account No. 1
Enable Sharing ON (Yes)
POP3 Mail Server Address	ms02.com
POP3 Mail Server Account Name	greatco
Password 9087654

Error! Reference source not found. "Mail User"

User ID	bjones
Password Secret064
Mail Account	1
Set as Recipient for Unrouted Mail	ON (Yes)

E-Mail Program

E-Mail Address	[e-mail]
SMTP Server(Outgoing Mail)	smpt09.com
POP3 Server(Incoming Mail)	192.168.0.1
POP3 Account bjones
Password Secret064

A Troubleshooting

This chapter covers some common problems that may be encountered while using the Error! Reference source not found. and some possible solutions to them. If you follow the suggested steps and the Error! Reference source not found. still does not function properly, contact your dealer for further advice.

Problem 1: I configured and installed the Error! Reference source not found. in the network, but I can't get it to respond.

Solution 1: If the configuration settings are correct, then you probably forgot to set the dip switches back to their Off positions after configuration. Power Off the Error! Reference source not found. and ensure that the dip switches are in their Off positions.

Problem 2: When I enter a URL or IP address I get a time out error.

Solution 2: Any number of things could be causing this. Try the following troubleshooting steps.

1. If this is first time you have used your browser, ensure that your workstations IP settings are correct, including IP address, default gateway and DNS.

2. Ping the Error! Reference source not

found.. Use the “Run” command to enter the following command:

Ping xxx.xxx.xxx.xxx

where xxx.xxx.xxx.xxx is the IP address assigned to the Error! Reference source not found.'s LAN interface.

1. If the ping command fails, check that the Error! Reference source not found. is connected and ON. If it is connected and on, there is a problem with your LAN.

2. Check that the Port is "Enabled" (Advanced Port Settings). If it is not, you need to use the HTML program to establish a connection.

3. Run your Browser and connect to the Error! Reference source not found..

Switch to the “Status” screen, and examine the Log. Details of the Log messages, and the possible causes of any errors, are shown in Appendix B - Log Messages.

Problem 3: My Modem/ISDN TA is working fine with a direct connection. How do I find what "Initial String" it is using?

Solution 3: Use the procedure described in Finding the current Initial String on page 60.

Problem 4: Data Transmissions are very slow.

Solution 4: Check and ensure that the Initial String is

configured to RTS/CTS flow control.

Problem 5: Some applications do not run properly when using the Error! Reference source not found..

Solution 5: The Error! Reference source not found. processes the data passing through it, so it is not transparent. Some programs may have limited functionality when used with the Error! Reference source not found..

The number of supported applications is being expanded as rapidly as possible. The following applications and protocols are supported by firmware V5.0:

Telnet, FTP, HTTP, ping

POP/SMTP, Archie, NNTP

TFTP, IRC, Gopher

DNS, SNMP, Real Audio

Normal Operation

The following sequence of messages is typical of normal operation.

send "ATDT 0123456789" CONNECT 115200 max phone line speed 28800 bps physical line is connected start PPP ppp up successfully

Error Conditions

The following messages indicate an error condition.

No dial tone

The modem could not obtain a dial tone. Check your connections on the phone line and the modem.

Busy error

The number dialed was busy. Check that the number is correct. If it is, try dialing later. If this occurs regularly, check with your ISP.

DCD low, DSR low

The connection was lost. This could indicate a bad line or poor connection. Normally, if a connection is lost, it will automatically be re-established, unless the “Dial on demand” setting is OFF.

PPP up fail

The ISP rejected the attempt at connection. Check that your username and password is correct. If it is, check with your ISP to see why the connection is being rejected.

Time out

No response. Check that the modem is ON and properly connected to the Error! Reference source not found..

No carrier, no answer

There was no response from the phone number dialed. Check that the phone number is correct, and the modem is working. If both of these are OK, check with your ISP.

C AT Commands

Required Settings

For the Error! Reference source not found. to function correctly, the modem must be set as follows.

Setting AT Command
Fixed baud rate setting	AT&B1
RTS/CTS flow control AT&K3
DCD to track the presence of a carrier	AT&C1
DTR off to hang-up modem	AT&D2
DSR always on AT&S0
Modem to return modem-to-modem data link speed	ATX4(see Note below)

Note: Modem-to-modem data link speed.

Multi-port models requires this information for the Bandwidth Utilization feature (in the Advanced menu options) to function correctly. For some Mircocom and other modems, the "ATX4" command above is not sufficient, and a non-standard "W2" command (no "AT") must be used as well.

For a modem which uses the standard AT commands shown above, the Initial String would look like the following:

AT&F&B1&K3&C1&D2&S0X4

The first command (AT&F) sets the modem to the factory defaults, to ensure a consistent starting point.

This command string (AT&F) is also the default value. It will work if the modem's factory defaults match the required settings.

Finding the current Initial String

If your modem is already working correctly, but you don't know what the modem initialization string is, you can use the following procedure to find out.

1. Select My Computer, then Dial-Up Networking.
2. Select the icon for your connection, then Properties.
3. Click the Configure button, then the Connection tab, as shown below.

Figure 16:- Connection Properties (W95)

1. Select Advanced to see the screen below.

Figure 17:- Advanced Connection (W95)

1. Check the option Record a log file. Then click OK and exit.
2. Use Dial-up Networking to make your on-line connection normally. A log file MODEMLOG.TXT will be created in your Windows directory.
3. Use Notepad or another editor to read and print the file MODEMLOG.TXT.
4. Examine the file to determine the Initial String and also if any Script commands are being used. See Appendix D - Script Files for information on script files. (Note: The Win 95 Dial-up Networking scripting language is more complex than that of the Error! Reference source not found..)

D Script files

This section describes the script file commands and syntax to be used when creating script files.

Script files are only required if your ISP does not use a standard PPP connection and authentication.

Commands

Three commands can be used to automate a proprietary negotiation process. The commands are as follows:

Send	Send [msec]
	Send a data string, with a. [msec] (milliseconds) delay between the sending of each character.
Wait	Wait [msec]
	Wait for the specified time (milliseconds) to elapse before executing the next script line.
Wait	Wait [msec]
	Wait for the specified time (milliseconds) to receive the string. If the string is not received within the specified time, the connection is reset. An error conditions arises if [msec] is not specified and the string is not received immediately.

Variables

Eleven special string variables can be used in conjunction with the command strings discussed above. The following string variables are supported:

Variable Description
\a alert
\b	backspace
\f form feed
\n	new line
\r carriage return
\t horizontal tab
\v vertical tab
\? Literal question mark
\' literal single quotation mark
\" literal double quotation mark
\\ literal back slash

Note: The strings and special control variables need to be enclosed in double quotes. Literal variables are used when ?, ', ", or \ are part of the string. For example, to send the string "User Name", the script file entry should be "\"User Name\"". Also, each script entry command, time and string, must be separated by a space.

Example Script File

The following is a sample script file with the proper syntax conventions. This script file could be used to log on to Compuserve.

wait 3000

send 100 "\r"

wait 3000

send 100 "CIS\r"

wait 3000 “:”

send 100 "user idAr"

wait 3000

send 100 "password\r"

wait 60000 “!”

send 100 "GO PPPCONNECT\r"
