Solved! Go to Solution.
For the internal nat rule you also need to add source nat to force the reply traffic back to the firewall. Otherwise the routing is asymmetrical directly back from the server to the source instead of through the firewall. This is known as U turn or hairpin nat. See this configuration example.
I am new to PA firewalls. Is the U-TURN NAT really working for you sicne I have not seen anyone stating that it works. As a matter of fact I saw this link which shows it does not work. No TAC in Palo Alto is able to help me yet or state that it works or does not work. Pretty frustrting.
DNS Doctoring feature does not work.
But I tried the workaround along with 3 different TACs and it did not work. Really appreciate any feedback.
