HA Setup with different Networkcard vendors

(1/2) > >>

c-mu:
Hi all,
I am planning a new HA setup for a branch. Is it possible to implement the whole thing with different hardware, specifically I imagine that server 1 gets a Mellanox card and server 2 an Intel. As far as I can remember, only the order and description of the interfaces must remain the same, or am I wrong?

The goal is that I want to spread the "risk" as far as possible, if there is a firmware bug or something similar, not both systems are affected.

Thank you!

The interfaces must have the same name on both machines. Name means "optXX", not the name or description you choose in the frontend.

c-mu:
Thanks, I think the opt names are assigned by OPNSense in ascending order, so there should be no problem with different networkcards, i just need to make sure the order is the same on both sides. so the theory.

No, also the driver names need to be unique or everything will fail:

I see.
I have a cluster running with one physical and the backup virtualized, yet it does seem to work for me.
How can I find out if pfsync actually works? In Virtual IPs -> Status I can see the same pfsync nodes for both machines.
