Hi Team,
We have a customer he is using U – turn NAT. He is facing issue with DMZ server to client server.( i.e both are in same zone)
He is able to access from DMZ to DMZ only that particular IP. He is not able to access remaining IPs.
I have checked the session logs I am observing in the session logs. Connection is getting aged out with the session end reason TCP-FIN and application is not getting identified.
Kindly help me to address the issue.
Thanks & Regards
Sasikumari.

could you illustrate what your U-Turn looks like?
for U-turn to work you should do both source and destination NAT (source nat to the firewall interface, so the 'server' replies to the firewall instead of the real source)
is the client connecting to a 'public' ip (or anything not in the local broadcast domain) and is NAT being applied properly in the session ?

Hello,
Possible use an internal IP address rather than a public IP that requires a U-Turn NAT?
