L3 Networker


i'am configuring a paloalto firwall wish is the backward firewall,

i'm facing problem with nat , users must be integrated in the frontal firewall

users passes by paloalto firewall first then the frontal firewall, when it pass by pan their adresses changes by nat , and the frontal firewall does'nt reconginze them ,wish is a hige problem

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

thank's in advance


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.
