"
When you choose WAN only or LAN & WAN , you still need to configure a
firewall rule to allow access.
To disable remote management of a service, select Disable in the corresponding Access Status
field.
You may only have one remote management session running at a time. The ZyXEL Device
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 SSH
1
Telnet
2 HTTPS and HTTP
23.1.1 Remote Management Limitations
Remote management does not work when:
• You have not enabled that service on the interface in the corresponding remote
management screen.
• 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 ZyXEL Device 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.
23.1.2 Remote Management and NAT
When NAT is enabled:
• Use the ZyXEL Device’s WAN IP address when configuring from the WAN.
• Use the ZyXEL Device’s LAN IP address when configuring from the LAN.
23.1.3 System Timeout
There is a default system management idle timeout of five minutes (three hundred seconds).
The ZyXEL Device 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.
