Remote Management
Configuration
This chapter provides information on configuring remote management.
21.1
Remote Management Overview
Remote management allows you to determine which services/protocols can access which
ZyXEL Device interface (if any) from which computers.
Note:
When you configure remote management to allow management from the WAN,
you still need to configure a firewall rule to allow access.
You may manage your ZyXEL Device from a remote location via:
Internet (WAN only)
ALL (LAN and WAN)
LAN only,
Neither (Disable).
Note:
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
Telnet
2
HTTP
21.1.1
Remote Management Limitations
Remote management over LAN or WAN will not work when:
You have disabled that service in one of the remote management screens.

Chapter 21 Remote Management Configuration
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.
21.1.2
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.
21.1.3
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.
