NOTICE
HAMACHI SHOULD ONLY BE USED IF NEITHER PLAYER HAS THE ABILITY TO HOST
All you need to host is an open/forwarded port 7500.
I agree, but before I reinstalled my system, I was not able to host a game. Strange thing, because I forwarded the port, even deinstalled my software firewall and deactivated/forwarded ports in the windows firewall. And still, I was not able to host.
After the system reinstall, it worked fine. It's not always the RTFM.
Jesus, I'm arguing against an admin. *runs*
