So I'm not at work anymore, but toribash doesn't work on my school wlan either. Veb mentioned a possibility to run servers on port 443 too. What is that port used for by default? Is there any chance to somehow use port tunneling to play toribash and how is it done? :O
EDIT: so I found out that port 443 is used in https-connections, and isn't blocked on our school wlan, or at least I can access https-sites. Dunno if multiplayer would work trough it.
Veb: I'll be hilighting you on IRC with a link to this thread, please don't get pissed about it =D
