I just moved into my college dorm, and I was trying to connect with iChat AV to my girlfriend in NYU, and we both got a few error messages, and weren't able to connect.
I believe the problem is the school firewall, but I don't know a solution to get through it. I think asking my IT department would be worthless, as they have very poor Mac support (I go to a tiny liberal arts school, so you can imagine the amount of mac users).
Anyone with similar experiences or know how to fix this?
Thanks

What do the error messages say that makes you think it is a firewall problem?

What else could it be? It worked before when we were home, we have identical Powerbooks with iChat AV and an iSight, and now that we moved in, it refuses to connect.
It just says stuff like Conference refused to start, or didn't accept, when she did.
I just figured that a lot of people had problems with the firewall, because most internet video chat/conference programs have problems getting through firewalls.

Quoting from here:
A "simple" firewall only allows you to open or close ports, without any additional criteria. If you have one of these, then you should open these ports:
5060, 5190, 5298, 5353, 5678, 16384-16403
This is how one would generally get through a firewall. Now, as you said, convincing (both) your schools IT department do this may be a quite a chore.
If there was some other easy way to get around it, wouldn't be much of a firewall now would it.

I just got a call about this same problem the other day. I work at the helpdesk at my school, and a father called asking why he couldn't use his isight with his daughter who lives in the dorms.
After a little research I found that my college blocks all udp traffic, and packet shapes tcp traffic on all ports. I'm not sure if the isight uses udp or tcp ( If anyone has the answer to this I'd appreciate it), but either way he was not going to be able to connect.
The only solutions I have found so far are to either a) try using yahoo messenger because it might use a less restricted port, or b) talk to your IT guys and ask them what you can do. It doesn't matter if they have poor mac support, this is definitely a network related issue.

Hey LORL,
I went through the same thing my Freshman year with my girlfriend being at a different school than me. Before, we could use our webcams easily over our internet connections.
But when I got to school, one that had a horrible, horrible network, I couldn't use my iSight because of crappy bandwith and a horrible firewall.
Thus I did some talking around and found the administrative proxy for my school network, and it helped a bit.
