Prestige 202 ISDN Router

11.2 Telnet Under NAT

When NAT is enabled and an inside server is specified, telnet connections from the outside will be
forwarded to the inside server. So to configure the Prestige via telnet from the outside, you must
first telnet to the inside server, and then telnet from the server to the Prestige using its inside LAN
IP address. If no inside server is specified, telnetting to the SUA™ 's IP address connects to the
Prestige directly.

11.3 Telnet Capabilities

11.3.1 Single Administrator

To prevent confusion and discrepancy on the configuration, your Prestige only allows one
administrator to log in at any time. Your Prestige also gives priority to the console port over telnet.
If you have already connected to your Prestige via telnet, you will be logged out if another user
logs in to the Prestige via the console port.

11.3.2 System Timeout

There is a system timeout of 5 minutes (300 seconds) for either the console port or telnet. Your
Prestige will automatically log you out if you do nothing in this timeout period, except when it is
continuously updating the status in Menu 24.1.
