For some reason the start button to start the firewall in Snow Leopard seems to be grayed out for me so I cannot enable it. Does anyone know why...perhaps another setting somewhere? I'm trying to host a game in Warcraft 3 but can't for some reason with firewall disabled and ports forwarded correctly. I was going to try and enable firewall and then let Warcraft be an exception. Will this work or does anyone know why I can't host?
