Ports blocked

Hello Everyone!

First of all, I tried to look for the answer to my question on the forums, but I couldn't find anything. I apologize, if someone already answered it. So my situation is this: I'm at university, and all ports are blocked, only a few of them are open (we can use facebook, and youtube and such, but that's kinda like it), so that means, I can't play World of Warcraft from here, which blows, considering I spend most of my time here. However, if I knew which ports the server uses, I could tell the administrator to open them, and I could play.

So does ANYONE know which are those ports?

Thank you for your answers in advance.

Check this.
I doubt your problem is in these ports, but you can try.

Those are a couple of the required ones. Last year though, I was playing on a different server, and I needed the server specific ports too, in order to play. Thanks for your answer. :)
