Hi,
we have a static NAT from this ip 192.168.200.8 (zone DMZ) to 195.57. (zone VPN). But we realised that the NAT rule which is matching is wrong.
Its matching the NAT rule (ftp.arag.es) 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???
regards

Hello,
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!

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
To: 192.57.58.218
Translate to: 192.168.200.8
