I am using BM3.7 with latest patches and NW6 SP2, plus some post sp2

We are trying to connect to a server outside our LAN and run a
application. I have created the necessary filter exceptions (very
destination host...from our source network) and tested them.

The application on the other side of the firewall needs a static
address to
return traffic to.

What I have done: I have added secondary ip addresses to the public
and used a mix of Static and Dynamic NAT.

When I am running NAT(running with or without filters), the
(using their front end application) login to remote Unix server, get
menu, but when you run the application, it times out.

If I disable NAT and have filters running, the workstations login and
application runs.

Is there something else I am suppose to configure?
