I don't think this can be done on Windows. I also don't think your
fireawll is blocking your outgoing ports, but looks at the port you're
trying to connect to, and blocks it then. It doesn't make sense to block
traffic coming from random ports, without knowing what protocol is used.

But... I'm not a firewall expert, so I might be wrong.
