You wont see your own server in the list, but other people will, its just how ASE works, also make sure your server is set to port 2003 to match the port you opened
Dont really no, i mean the site itself is pretty self-explanatory, just search for your router on http://portforward.com/english/routers/ ... rindex.htm and select mta, it will give you step by step (with pictures) instructions
The game doesnt have NPC or Computer controlled players, however you can play as a cop, civilian etc and you can also join gangs of people, every person you see ingame on MTA is another player, playing from somewhere else in the world
