Well, the other option here is to run a protocol specific proxy on your firewall machine. There are a number of SIP proxies available, such as siproxd or a full Asterisk setup.

Ah, gotcha. It's not "my" firewall, there's no way I could configure the firewall, and there are no exceptions made even if asking for some.
And this is the situation for many - people that are using an Internet connection that goes through firewall X somewhere (like, in a basement of a group of flats, behind locked doors) that cannot be configured in any way.
