The following table describes the labels in this screen.

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.
