Check your IP, is it local? I tried hosting games before, I never was able to get my friends in it, until I relized I was giving them the wrong IP. As for joining through the Lobby, the only advice I have is check your port settings, and watch the firewalls, If you're lucky, you can probably set halo so it allows anything in or out. But if you don't, then just turn it off.
