Message from my university IT people explaining why Starcraft II wont work on campus, does this sound plausible? so ya the results are the same no matter if I'm hosting or not, I'm able to connect but then I lag out. So at least some connections are being made.
If there's any sort of diagnostics or tests you think I could do on my side of the network to probe this further let me know, I'll get you the results. I looked at a wireshark dump from a game and it seems to me like everything is getting through the network just at throttled speeds.
