Description (partial)

Symptom: ACE module configured for ftp inspection and nat. In routed mode. Swhen a server behind the ace acting as an ftp client makes a connection to a server outside the ace, the active data channel fails. What is observed is that while the control channel messages are properly fixed up with ftp inspection, when the server opens the data channel with a syn to the natted port, the ace sends this syn along to the client it translates the ip but does not translate the port.

Conditions: ace in routed mode with ftp inspection and dynamic nat.
