How can I open a port 50000 on ISA 2004 running on SBS 2003 server ?

I was running Xampp on the server before we had ISA installed. The old LAN network was simply all PCs and server on same network card and a Router to internet. Apache, Mysql and php were installed and running fine. We were using port 50000 for our application.
Now a second Network card is installed with LAN on one card and Router on the other with ISA 2004 acting as the gateway between them. I need to know how I can open port 50000 so that I can get the apache server running again (data is sent to the server externally from PDA to port 50000).

Thanks in advance.

With ISA 2004 you can create custom protocols.
I don't specifically know ISA on SBS but the theory will be the same:
Under firewall policy, in the toolbox select protocols, user defined, new, protocol
Go through the Wizard
protocol type is TCP, direction outbound and the range is 50000 to 50000
next next, no secondary connection, next finish
create a rule for inbound from external NIC to Apache Server using port 50000 for all users
