L2 communication spanning two firewalls

L1 Bithead

Hello,

 

I have the architecture outlined below, and communication needs to be established between the machines on the network 10.1.2.0/24 via FW1 (Palo Alto) and FW2 (fortigate). Could you please offer a solution to accomplish this?

On the Palo side you have the option of using a VWire (2 interfaces connected as a virtual wire), or setting 2 interfaces to Layer2 mode and putting them in the same vlan

in both cases give each interface it's own zone and then create 2 security rules 

zone a to zone b

zone b to zone a

 

and it will work like a charm

 

on the forti side you probably need black magic (sorry, you'll need to go ask fortinet)

This method is similar on the Fortigate. You can assign layer 2 vlans to ports on the forti.
