15.4 VPN and Remote Management
You can allow someone to use a service (like Telnet or HTTP) through a VPN tunnel to
manage the NBG420N. One of the NBG420N’s ports must be part of the VPN rule’s local
network. This can be the NBG420N’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 NBG420N’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 NBG420N’s LAN interface. Remote
management must also be configured to allow HTTP access on the NBG420N’s LAN
interface.
