i tried to delete nat because the outside interface of pan is also a private adress , but traffic don't pass when i do this

so i want toknow if i can allow traffic to pass without nating , or if pan has someting called (no nat) like asa and juniper

please help me to figure it out

As you have introduced a new L3 Device (PA FW) in the Network. The Frontal firewall does not know how to route back the return traffic.

Source-NAT on PA firewall was taking care of this return route earlier.
