14.16  VPN and Remote Management
You can allow someone to use a service (like Telnet or HTTP) through a VPN tunnel to 
manage the ZyWALL. One of the ZyWALL’s ports must be part of the VPN rule’s local 
network. This can be the ZyWALL’s LAN port if you do not want to allow remote 
management on the WAN port. You also have to configure remote management (REMOTE 
MGMT
) to allow management access for the service through the specific port. 
In the following example, the VPN rule’s local network (A) includes the ZyWALL’s LAN IP 
address of 192.168.1.7. Someone in the remote network (B) can use a service (like HTTP for 
example) through the VPN tunnel to access the ZyWALL’s LAN interface. Remote 
management must also be configured to allow HTTP access on the ZyWALL’s LAN interface.
