After some advice, planning to have 2 X PA820 pairs of Active/ Passives, Inner and outer firewalls protecting some internal networks.
See the diagram, Does the HA2 link pass data plane traffic at all? Or can it?
There could be a scenario that one set of FW's can failover and the primary unit of one trying to speak to the standby unit of the other.
Or is the only solution to put a switch in between the green cables FW Connect to stop this issue?
Great, thanks for the advice BTW,
I should be able to keep the interface on the Palo Alo set as Layer 3 shouldnt i? Or will I have to change to a L2 interface ? I need to be able to have a IP address on the interface for the static routing.
L2 VLAN, vlan id 555 for example, and all 4 ports will sit in that VLAN.
