Opening a specific port on all machines in a domain via group policies

I feel a little lost with this one...not even sure if I can do what I'm trying to do.

I'm trying to configure all the computers within the domain to open a certain udp port(required for a network agent to run). My first guess was to go to the group policy in SBS2003 and try mucking about in there....few seconds later I realized this isn't as cut and dry as it had seemed before. The interface confused me silly.

How do I automatically congfigure group policy to open the specified port via policies, or is this even the right way to go about opening the port on all the workstations?

I can go around opening them manually on each machine...but I'd rather do it thru the server.

In the Server Management, head over to Advanced Management, Group Policy Management, Forest, Domains, YourDomain.Local.  On the right, find the policy called Small Business Server Windows Firewall.  Right-click on it and choose Edit.

Look under Computer Configuration, Administrative Templates, Network, Network Connections, Windows Firewall, Domain Profile.  On the right you'll see Windows Firewall: Define Port Exceptions.  Double click it, and you'll see the instructions for proper syntax.  You can also use Define Program Exceptions to specify the path to the program instead of just a port (but only do this for trusted programs that are safe to expose completely).
