Chapter 18 Remote Management
NBG-460N User’s Guide
248
18.3  What You Need To Know
You may only have one remote management session running at a time. The NBG-
460N automatically disconnects a remote management session of lower priority 
when another remote management session of higher priority starts. The priorities 
for the different types of remote management sessions are as follows.
1. Telnet
2. HTTP
Note: To disable remote management of a service, select Disable in the 
corresponding Server Access field.
18.3.1  Remote Management Limitations
Remote management over LAN or WAN will not work when:
1
You have disabled that service in one of the remote management screens.
2
The IP address in the Secured Client IP Address field does not match the client 
IP address. If it does not match, the NBG-460N will disconnect the session 
immediately.
3
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.
4
There is a firewall rule that blocks it.
18.3.2  Remote Management and NAT
When NAT is enabled:
• Use the NBG-460N’s WAN IP address when configuring from the WAN. 
• Use the NBG-460N’s LAN IP address when configuring from the LAN.
18.3.3  System Timeout
There is a default system management idle timeout of five minutes (three 
hundred seconds). The NBG-460N 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. You can change the timeout 
period in the System screen
