Easiest way to "port forward" is to just download utorrent > go to preferences > on the right part, you will see a box with some numbers written on it. Just change the number to the port you want to open/forward and then remove the check box of -- use random port. This is done.
Now to use it, start your sa-mp server and then start utorrent. Your server will be online. You can test too.
IMPORTANT :- start utorrent AFTER sa-mp server. Or else sa-mp server will tell that no filterscripts were loaded and no gamemodes were loaded.
By starting utorrent after sa-mp server, i mean quitting the small icon on taskbar too.
If you just quit the utorrent, wait for around max. 5 minutes then start server and then start utorrent again.
Hope i helped you
