Note that your router needs to have UPnP enabled.

UPnP-PortMapper

UPnP-PortMapper is a Java application which makes port forwarding easy. It works on Windows, OS X, Linux and *BSDs.

Note that your router must support UPnP and it must be enabled. On most routers, it is enabled by default.

Download link: here

Download it then run it with Java (right click > Open With > Java). On Linux, make sure it is executable -- if it is not, then type this after using the "cd" command to go to the folder where you placed the .jar file:


upnpc

upnpc is a command-line tool for Linux and Windows. It can be found in distributions' repositories (at least for Debian/Ubuntu, probably other distributions too).

Download link for Windows: here

On Linux, just install it using your package manager.

Instructions:

Add port forwarding:

(you can see your internal IP with "ifconfig" on Linux, "ipconfig" on Windows)

List active port forwardings:


Remove a port forwarding:

The same can be achieved by entering this command:

without java or any other bloated shit.

Works too, but that's Linux-only (edit: nope, nevermind). Added to the topic, though.

It is better to do port forwarding in your router, and not deal with uPnp; but this is nice...

Using UPnP-PortMapper, I got this error:

I followed the instructions exactly like you said.
I run windows 7.

"InvalidArgs"... maybe some argument in your port forwarding preset was empty or invalid (eg. a word instead of a number as port). Or your router doesn't have UPnP enabled.

For the security conscious, see show 389 of Security Now. Within the first 3:30 I was aghast at the number of vulnerable routers out there.

It's not possible for someone from the Internet to port forward unless you've got some malicious software on your machine. And as always... crackers have better things to do.

Port forwarding isn't the issue, it's a vulnerability in the uPNP protocol that allows the device to be compromised. H.D. Moore has a paper out on it last Tuesday outlining the issue and how many devices were found to be open to the issue during a five month scan of the Internet:

We've known for a couple of years how much upnp swiss cheese's a router, but not to this extent until last week.
