NAT rule being applied wrong



we have a static NAT from this ip (zone DMZ)  to 195.57. (zone VPN). But we realised that the NAT rule which is matching is wrong.

Its matching the NAT rule ( but this rule has a filter by "Destination zone" Externa. And the real traffic is VPN<->DMZ


Why PA is applying this rule if not being include the destiantion zone in the filter???

I'm guessing you need a U-Turn NAT rule so the VPN clients can communicate properly to the external FTP site.


This is a good article and covers all the NAT types.


Hope this helps!

Re: NAT rule being applied wrong

when you create a bidirectional policy, a return policy is created in the background. You can see it just using the CLI 

> show running nat-policy

The return policy changes the destination zone to any and put it as source. so In your case the return policy is going to be

From zone: any

To zone: DMZ
