Port Forwarding
Port forwarding enables you to make services from applications in your local network avail-
able to Internet users as well. The router can use a specific port to automatically forward
incoming requests from the Internet to a PC in the local network and thus set up a virtual
server, for example to publish your Internet page on your own Web server.
Internet services are generally addressed via defined port numbers. The router requires a
mapping table for the port numbers in order to divert the service requests to a PC that
actually provides the service. You can create these on this Web page.
