i have a router and im behind a fire wall. i know that u click on the old connection option to make it so i can connect 2 other people. that works only once then i have 2 change it over and over again every time i want to rejoin a room that some1 is hosting. its not that the option changes every time. i have 2 take it off of the old connection, then put it back on. it doesnt matter if i check the "i am behind a firewall or proxy" box or not. same thing happens every time. also, the quick battle option has only worked 4 me once. after that it didnt.
