^ what?
uhh anyway, yeah you put the start and end port (start 7776 end 7778) and then you put ur lan IP address (the address when u type ipconfig of your computer, not gateway)
then you need to find your external IP (ipchicken.com), and then tell whoever, to connect to that IP and that port
eg 202.46.78.111:7777 , thats the connection info they'd put for SA-MP.
as for the torrent creation, click here I just googled "how to make a torrent" search that on youtube as well someone made a video.
