Connect to Remote Sites; Even During LAN Failures; with the NetGuardian 832A

You can't correct problems that you can't see, so it's essential to maintain constant visibility of your network devices, even when your primary network connection is down. If your LAN connection to your remote sites fails, you can still keep in touch with your remote equipment by using your NetGuardian 832A as a PPP (Point-to-Point Protocol) server via dial-up.

Using the NetGuardian as a PPP server, you can connect to your remote devices via Telnet and perform diagnostics, troubleshooting, and corrective procedures. No matter what the status of your LAN, you'll still be able to detect (and possibly even correct) remote site problems before you dispatch a technician.

To configure your NetGuardian as a PPP server, follow these steps:

1. Log on to the NetGuardian Web Interface
2. Click on the Edit menu
3. Click "PPP" in the Edit menu

4. Under Server, click "Enable Server" (also known as Hosting Mode.)

5. Set IP address that is given to the guest dialing in. (This must be a valid and available IP address for the subnet on the LAN you will be connecting to - the same one the NetGuardian is connected to.)
6. Click "Submit Data"

7. Click "Ports" on the Edit menu
8. Under Modem, change the "Ring Count" to greater than 0

9. Type "&Q6" in Answer Init String box.
10. Click "Submit Data"

11. Click "Logon" in the Edit menu

Note: There can be up to 16 different user names and each one must have its own password.

12. Click the "Available" link to set up each user you want to have access.

13. Set user name, password, and privileges.

Note: User name and password must be different from the master user name and password.

14. Make sure privileges are at least PPP and Telnet.

15. Click "Submit Data"
16. Click "Reboot" in Edit menu

You also need to configure your remote terminal modem in order to access your NetGuardian by following these steps:

Windows 98 users: set baud rate to 9600.

Windows 2000, XP users: in modem configuration general tab uncheck "Enable modem error control" and "Enable compression."

Mac OSX users: use standard dial-in.
