High availability / pfSync and Transparent Filtering for HA in a complex network

« on: November 16, 2022, 11:00:38 pm »

I am wondering if I can use two OPNsense firewalls in transparent mode, synchronized with pfSync.  I read the HA documentation and it seems to exclusively deal with CARP. 

I know I can do this with more expensive cisco, Juniper, or Palo Alto firewalls, but I'm hoping to spend less (money) for a solution that is free-er (as in speech.)
