Connection on Mac and PC HELP!!

I’ve uploaded a game to http://www.UniteGames.com
and it is based on the M2H tutorial, though it seems to work locally.
if my Windows 7 64 bit computer hosts a game, no one is able to join in.
if my mac is hosting everyone can join,

I have disabled the firewall on my windows 7 pc, i know that this might be a windows problem, in that cause does anyone know what it may be.
So i might write a help on connection on the page.

Have to ask, so i know it is a PC problem and not a unity coding problem, i’ve been over the code again and again, and cannot see any error’s or anything that may cause this.

Thanks in advance.

If you don’t like turning the crummy firewall (opinions vary) off that windows comes with, just add the game as an exception to your firewall. If its a web based game, I believe you just have to add an exception for the browser.

Your windows machine will probably have a different network IP so make sure you have forwarded your ports on the windows IP in your router.
