I cant host a game... what should I do with my router and I already tried opening the ports and disabling the firewall, im stuck, any suggestions???

When you say you can't host a game i presume you mean that no-one can join your game..

We need some more details about what your trying to do - in-game server - dedicated server ?

im guessing you are just hosting a server and no one can see/join.

the problem is just in your firewall or...idk whatever

you need to take the port number when you are starting the server, and make a hole in your firewall with that port number.

I think thats it, I dont quite rememeber, by brother did it for me

If your firewall is NAT based then you need to set up a port forward to the correct machine.

The Angry Angel put together a thorough guide, stickied in this section of the forum. Review the guide carefully since what's needed to host an LFS server is addressed there. Maybe that will help identify more precisely the issues that are preventing you from hosting a game.
