Hello,
is it possible to create an 3 node HA stack?
From here it sounds like possible
QuoteOPNsense utilizes the Common Address Redundancy Protocol or CARP for hardware failover. Two or more firewalls can be configured as a failover group. If one interface fails on the primary or the primary goes offline entirely, the secondary becomes active.

But i cant find any example, questions or topics for this.
How can we achieve this? Are there any guide we can follow? Any experiences?
Thanks for Help!
I was just about to ask this too!
It seems trivial to do with CARP, but I don't see a way to sync any of the info to more than 1 node using PFSync :(

For me its not perfect, but it works.
Sync the config from Node 1 to 2 and from 2 to 3 works fine. You just have to be careful with changes while Node1 is offline.
For the connectionsync (pfsync) just use a multicast network.
So there are no node limits.
