NBG-417N User’s Guide

Port forwarding allows you to define the local servers to which the incoming 
services will be forwarded. To change your NBG-417N’s port forwarding settings, 
click Network > NAT > Application. The screen appears as shown.

Note: If you do not assign a Default Server IP address in the NAT > General screen, 

the NBG-417N discards all packets received for ports that are not specified in 
this screen or remote management.

Refer to 

 for port numbers commonly used for particular 

services.

In addition to the servers for specified services, NAT supports a default 
server. A default server receives packets from ports that are not 
specified in the Application screen. 

If you do not assign a Default Server IP address, the NBG-417N 
discards all packets received for ports that are not specified in the 
Application screen or remote management.
