•A filter in SMT menu 3.1 (LAN) or in menu 11.5 (WAN) is applied to block a Telnet, FTP or Web service.
•You have disabled that service in one of the remote management screens.
•The IP address in the Secured Client IP field does not match the client IP address. If it does not match, the Prestige will disconnect the session immediately.
•There is already another remote management session with an equal or higher priority running. You may only have one remote management session running at one time.
•There is a firewall rule that blocks it.
13.1.2Remote Management and NAT
When NAT is enabled:
•Use the Prestige’s WAN IP address when configuring from the WAN.
•Use the Prestige’s LAN IP address when configuring from the LAN.
13.1.3System Timeout
There is a default system management idle timeout of five minutes (three hundred seconds). The Prestige automatically logs you out if the management session remains idle for longer than this timeout period. The management session does not time out when a statistics screen is polling.
13.2 Telnet
You can configure your Prestige for remote Telnet access as shown next.
