It depends on what you intend to do.

If you want to allow port 12002 outgoing, you need the following:
Goto Firewall rules  - right pane - toolbox - protocols
Click on new - protocol to create a new port definition
1.) Assign a name (myProtocol)
2.) Create a protocol definiton TCP outgoing from 12002 to 12002
Next - Next

If you have a general rule, which allows all outgoing traffic, thats is.

Goto Firewall rules  - right pane - task - new access rule
1.) Assign a name (myProtoco)
2.) allow
3.) Selected protocols --> select your new protocol
4.) From Internal (maybe also local host)
5.) To External
Next - Next

To allow traffic from external to internal:

Click on new - protocol to create a new port definition
1.) Assign a name ( MyProtocolServer)
2.) Create a protocol definiton TCP incoming from 12002 to 12002
Next - Next

Goto Firewall rules  - right pane - task - publish new nonWeb server
1.) Assign a name (myProtocol In)
2.) add the IP of the publishing serer192.168.225.1
3.) Select the new server protocol
4.) From External

For Keith Alabaster, it is originating from outside.

Thanks Alex - the second obvious question that has to be asked before ANY answer can be given to your enquiry, is about the version of ISA server you run? If it is ISA 2004 or ISA 2006 then bembi's response to you may suffice but if it is ISA2000 then it will not.

From Bembi solution, for this situation, which is the publishing server?

The internal server holding the service that you wish to connect to or the computer that should be the receiver of the port 12002 traffic that has originated from the Internet.

As Keith said....

Sorry, I copied an IP address into my rules... :-))
Use the second description: "To allow traffic from external to internal"
Where I put in 192.168..., set the IP address of your internal server, who hosts the application you want to access.
