WGR614 v6 Manual: Security

The WGR614 v6 router is equipped with several features designed to maintain security, as described in this section.

Computers Hidden by NAT
NAT opens a temporary path to the Internet for requests originating from the local network. Requests originating from outside the LAN are discarded, preventing users outside the LAN from finding and directly accessing the computers on the LAN.

Port Forwarding with NAT
Although NAT prevents Internet locations from directly accessing the computers on the LAN, the router allows you to direct incoming traffic to specific computers based on the service port number of the incoming request, or to one designated "DMZ" host computer. You can specify forwarding of single ports or ranges of ports.
