Forwarding Rules

The forwarding rules section deals with NAT traversal. Using the Virtual Server settings port forwarding can be configured. Special

AP settings can be used to configure port triggering. In the Miscellaneous section a DMZ host can be configured and UPnP can be

enabled or disabled.

Virtual Server

The Virtual Server page allows you to direct incoming traffic from the Internet side (identified by Protocol and External port) to the

internal server with a private IP address on the LAN side. The Internal port is required only if the external port needs to be converted

to a different port number used by the server on the LAN side. A maximum of 20 entries can be configured. In addition a series of

pre-configured commonly used ports can be selected for easy setup.

Special AP

The Special AP page allows the router to be configured for port triggering. Port triggering allows a client device connected to the

router to dynamically and automatically forward a specific port back to itself. Port triggering opens an incoming port when your

computer is using a specified outgoing port for specific traffic. A selection of common port triggering settings come preconfigured

on the NF2 for easy setup.

OPTION

DEFINITION

Trigger

Enter the outgoing trigger port be opened by a device connected to the router.

Incoming Ports

Enter the incoming port number or port ranges. For a port range use a dash (-) between the lower and upper

range numbers; e.g. 5000-6000. Use a comma between multiple numbers.

Enable

Select this option to enable or disable the port triggering rule.

Table 21: Advanced - Forwarding Rules - Port Triggering Settings

Miscellaneous

The miscellaneous page gives the user the option of enabling or disabling UPnP protocol or the option to assign a device connected

to the router as a DMZ host. A DMZ host is a host on the internal network that has all ports exposed to a WAN connection, except

those ports otherwise forwarded.
