Little Confused

[viper359]

I am looking to do a HA setup
Master will be a Proxmox VM
Secondary will be a physical Sophos XG450 appliance

Do I understand right, because the interfaces on each machine will probably be named different,
high availability wont work?

You can create a lagg interface with a single member from each physical or virtual port forcing the names to be identical.
