Palo Alto/Xbox/"Strict NAT"

["Tornoe, Eric J." <EJTORNOE () STTHOMAS EDU>]

Hi all,

We recently implemented a Palo Alto 5060 NGFW. We also transferred NAT to this device. We are now finding that we are 
having trouble with game consoles and games that use UPnP. In Microsoft terms our NAT is now "Strict", whereas before 
(using Cisco ASA) it was termed "Moderate".

Palo Alto acknowledges this issue and offers a solution- 1-1 NAT mapping- but this is not an ideal solution for us. 
They also spoke of using DIP (Dynamic IP)  instead of DIPP (Dynamic IP and Port) but this is not a simple solution in 
the short term.

I know there are a lot of other Palo schools out there so my questions are: Is this an issue for you? If so, how are 
you handling this? 1-1 mapping? Not using NAT? etc.

Thanks,

Eric
