BaUPnP

Many network programs require that one configure port forwarding in the router. Setting port forwarding in the router for your server application can be a challenge. Fortunately, most routers support a standard called Universal Plug and Play (UPnP). BaUPnP is a free tool that automates the process.

The tool, by default, configures port mapping for the two ports used by Web-servers - that is port 80 (HTTP) and port 443 (HTTPS). BaUPnP can also do port mapping for other ports by simply specifying the port mapping as command line arguments.
