CARP on two different PCs.

[DarkCorner]

I'm doing some testing at my house.
I have OPNSense on an Acer PC with i5, 8GB RAM and an additional 4 NIC card.
I would like to implement CARP with a second Acer PC of a different model, always with an additional 4 NIC card.
Is this possible, even if they are not exactly the same?

I have a Zenarmor "Home" license on my PC, can I manage it on the second PC? As?
