Hello Experts
I am just wondering, what is the order of different NAT on same packet. Lets say I want to do destination NAT and source NAT for the same packet. What NAT will happen first destination NAT or source NAT?

Hiya,
There can be multiple NAT rules configured on a PAN-OS device. NAT rules are evaluated top down like security rules. Once a packet matches a NAT rule, any other NAT rules configured are skipped for processing. Therefore, more specific NAT rules must be at the top to the rule list. Source:

Hello
What I mean I am doing double NAT (source and destination NAT on same packet) like for u-turn NAT:
1- User and server are in same subnet in trust zone (10.10.10.0/24). Interface IP of firewall is 10.10.10.1 and server IP is 10.10.10.10
2- User access the server public IP 2.2.2.2 that is in Untrust Zone
So I need to confiugre destination NAT from from 2.2.2.2 to 10.10.10.10 and then source NAT so user IP translated to 10.10.10.1 (firewall interface IP). Source NAT is for symmetric return means server should not give resonse back to direct user
When I confiugre NAT rule for destinaion NAT and source NAT. What would be the direction of each NAT?
