Port forwarding working only with UDP

Dear sirs,
I have setup a port forwarding via SNAT from an external interface IPv4 address to an internal server in a trusted interface.
Using netcat to test the port forwarding, it works, but it does not work when sending TCP messages. SNAT has been configured for both TCP and UDP ports.
Can you give me some help on how to make it work or what I might be doing wrong?
Thank you!

    Should work.

    Please post a sample deny log message for a TCP port that isn't being forwarded.

    You can turn on Logging on your policy to see packets allowed by it in Traffic Monitor.
