wc3 hosting

I want to host a game on Warcraft 3 Reign of Chaos.But it wont let me,I cant take my firewall off.?
I cant take my firewall off because My dad wont let me.What other way Can I do to let me host on Wc3?
Well, if you want to host on WC3 you have to open ports 6112-6119. See if you’re allowed to do that. I can’t host either, and my dad won’t let me open the ports
. But that’s what you have to do.
