Prestige 128+ ISDN Router

14.2 Telnet Under SUA

When Single User Account (SUA) 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 insider server is specified, telnetting to the SUA's IP address
will connect to the Prestige directly.

14.3 Telnet Capabilities

14.3.1 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.
14.3.2 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.
