Some network programs require that you configure port forwarding in your router, so that they will work properly. This is confusing to many people, causing many newcomers to give up
For those who know what they are doing, it is time consuming. There is a quicker and easier way.
Fortunately, most routers support a standard called Universal Plug and Play (UPnP), meaning that you can use the BaUPnP tool to update your port forwarding settings, without going through all the menus in your router.
BaUPnP is a free command line utility that automates the process of forwarding your ports.
The tool, by default, configures port mapping for the two ports used by web-servers - that is port 80 (HTTP) and port 443 (HTTPS). You are able to use your own arguments for any service you want.
The following example configures port mapping for FTP (port 21) and Telnet (port 23):
BaUPnP.exe 21 23
It doesn’t get much easier than that
