Opening ports for clients when using XP ICS

as far as i know XP's ICS doesn't block anything. It just monitors traffic and if it finds something bad, it'll then block it. Well if you know how to open ports via that Advanced tab or something, where it asks for internal and external ports. All you have to do is find out which program runs on which port. Both the internal and external ports for the program will be set the same AFAIK, because then for internal ports you start getting into something different where the local program runs on a different port, but when it sends the info to the local network server, the server attaches to the packet which port to enter thru the program's server with...well all we want to do is find out which program runs on what port and set both the internal and external ports to this port.
Download a program called Active Ports. It shows you what programs run on what ports. It has a row for Local port and one for Remote Port. Usually they are both the same but occasionally they are different for certain programs. Just configure your XP firewall settings to the details that this program gives to you.
Or to be even safer I'd download a 3rd party firewall (I recommend Tiny's Personal Firewall) because I don't really trust the XP's one all that much.
Anyway, whichever way you decide to go I'm hoping I've helped and not confused you too much :)
Btw, if you can't find a copy of that program PM me with your e-mail address and I'll send it to ya.At the request of wiggo ;)

sounds like you want to do port forwarding
if u want direct connections to PCs behind a firewall, you will need to setup port forwarding, not just pass-thru support. the only problem with port forwarding is that only 1 PC behind the firewall can have that port forwarded to them...
not sure about DCC transfers but I just give up on them, i can receive DCCs fine thru my firewall, but sending is a no-go
so, port allowances are fine for services that you wish to connect to, but u will need forwarding if you want to host the service yourself.
if that facility isnt in WinXP-ICS, then try this little app call AnalogX PortMapper, it works great and is free - www.analogx.com
again, all you'll needa know is what port services are running on, and that app grim told you about should tell ya wot u needa know
