I'd like to some information on configuring my firewall to work with Phex. Is it as simple as opening up certain TCP ports? I have checked the box in settings|options|firewall/proxy that says "Host is behind firewall." However, I suspect that my connections are still being limited.

I don't use Mandrake's firewall, but I my computer is connected to a Belkin Router with a built in firewall. The router is connected to a cable modem.

If it is as simple as allowing certain TCP ports, which do I need to allow?

I'm using Phex 0.9.0.40 with Mandrake 9.1. I have Java SDK 1.4.1_02 installed.
