3 ASA firewalls in failover or cluster??

We have 2 sites with 2 ASA 5520s on Site A and a 3rd ASA 5520 on Site B.


We have the 2 ASAs at Site A set as Active/Passive failover.


We would like the firewall at Site B to also be part of this failover in the event of Site A being unavailable. Is this possible?


We have a dedicated link between the 2 sites so linking the firewalls for heartbeats etc.. is not an issue.


Is this a valid setup? Is there a better way to achieve this?

This is not possible. You're better off using routing to control ourbound routing around a failure. Use object tracking to generate the default route and redistribute into your IGP.


On the outside NAT to unique address space and you're good to go.
