Connect Kopete throughout a proxy (or tunneling by http)

Hello to everybody

This is my first post in OpenSuse!!

I am living in a residence where the wifi connection it´s by a proxy. Firefox, Amarok, etc work well with internet, but Kopete still without connection. I think that it there is some port blocked (I am not an expert, just a curious :P)

So, I read that is it possible tunneling the connection by http? Is that possible?, and how to do that?

I am using Opensuse 11.2 with KDE 4.3.3

Thanks to all.

And it´s a pleasure be part of Opensuse community…
