Here is what I'm needing to do. I have a system behind the Firewall enterprise that I need to be able to talk with a system on the outside.
It needs to be able talk all ports both TCP and UDP just as if there was not firewall between those two machines.
other machines behind the firewall do not need to communicate with that machine on the outside, Just the designated machine.
All machines on the inside are NATed behind the firewall.
