oh, boy, i have no idea how that works, but i hear other people doing it. i only do PC, but i have the same problems with those sometimes too, and all i know is the whole system of running a private server is way erratic - sometimes it's smooth, sometimes i have problems (like it was running fine yesterday?! LOL). last time i couldn't get on mine for days (but my daughter could on her computer), i finally turned off the firewall on the host computer completely, and that solved it. try just turning off the firewall, if that works, then you know that it's a firewall issue and not a port forwarding issue. my issues are more related to the fact that i'm playing the game on the same computer i'm hosting with, and that gets touchy.
