Connecting Through a Telnet Connection

You can access the built-in interface by a Telnet call from any TCP/IP workstation on the LAN or
the remote network. In order to use the Telnet Protocol, you must know the current IP address of
the router. If the router does not have an IP address, you must first use a serial connection or the
FirstGear utility to assign an IP address. The router is shippped with a default address of
192.168.0.1.
To make a Telnet connection from the LAN, you must set up your workstation to reach the
IP address of the router by doing one of the following:
• Set your workstation to an IP address on the currently programmed subnet of the router.
• Add a route to the static routing table of the workstation to indicate that the router can be
reached through the local LAN port.
Note: If you change the LAN IP address of the router while connected through Telnet,
you lose the Telnet session. You must then open a new Telnet connection to the new
IP address and log in again.
When using Telnet, consider the following:
• Single administrator
To prevent confusion and discrepancy on the configuration, the router allows only one
terminal connection at any time. The router also gives priority to the RS-232 connection over
Telnet. If you have already connected to the router through Telnet, you are logged out if
another user then connects through the RS-232 cable. You can use a Telnet connection only
after the other administrator has disconnected.
• System timeout
When you are connected to the router through Telnet, there is a system timeout of 5 minutes
(300 seconds). If you are not configuring the device and leave it inactive for this timeout
period, the router automatically disconnects you.
