Is there a 'proxy arp' interface command (or equivalent) to allow l3 communication between isolated devices on private VLANs?
I am looking to move our DMZ to a private VLAN. I would like all ports to be isolated, but allow some communication between certain machines. This is where I would generally set up 'proxy arp' on the router to allow l3 communication, but I do not see this option on PA. Is there a way to set this up?

This is usually done with NAT on Palo Alto:

Also you can test the U-Turn NAT option:

Thank you for the input, and sorry for the super late reply, I somehow missed this notification.
I am not quite clear how those articles relate to my issue. In this scenario would I create a NAT policy that applies to the PVLAN so that the PA responds to all ARPs but not actually set a translation address?
