Prestige 128IMH ISDN Modem/ Router/Hub
13-2 Telnet Configuration
13.2 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, telnet to the SUA’s IP
address will connect to the Prestige directly.
13.3 Telnet Capabilities
13.3.1 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.
13.3.2 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.
