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.
For use: On the computer you want the ports to be forwarded to, open up your command prompt and navigate through to the folder you have saved BaUPnP.
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!
As this program changes the port forwarding settings to your router, this program only needs to be run once. This is not a program that will clog up valuable resources after you have used it.
You are able to run it from multiple machines, each offering various services. Just keep in mind that you can’t use the same port from two computers. You will also need to ensure that UPnP is turned on in your router settings.
