Cant host WC3 on my MAC

[frannyman]

I can't host WC3 on my apple 24" iMac. Can anyone help me out here? I also have a router.

The router is the problem.

You need to open ports 6112-6119 both ways on your router in order to allow people to join your games. OS shouldn't matter.

What router do you use?
