Does anyone know how to configure Microsoft's firewall (either in XP SP2 or Vista) to allow DVB-Dream and WinCSC to access external card sharing servers?

In XP I had to disable XP's firewall and replace it with Comodo Firewall to get WinCSC to work. In Vista, Comodo only have a beta version so far and it only recognises DVB-Dream's initial attempts to connect to their update server, but not when WinCSC tries connect to CS servers for scrambled channels.

I assume some of you configured the firewall in XP for this purpose, so please I need your help in this.
