How to ensure continued connectivity when LAN interface on primary unit goes down?

[mike_vc]

If LAN interface on primary unit is down, and backup unit CARP status for that interface becomes MASTER, but primary unit's WAN interface is still in MASTER status, how does sNATing to WAN VIP work? Is there a way to tell pfsense to make backup unit MASTER for all interfaces?

All other interface should follow then. So all interfaces on the primary should go into backup status.

If this is not the case, something is wrong in your setup.
Ensure that the WAN interfaces of both nodes can reach each other on layer 2.
