Hi,

I am thinking to add 2 mini pc nodes with dual NICs and create my first ever proxmox cluster.
I am already running pfSense on my single node.
to do HA on pfSense, you need a sync interface. This would mean that I need 3 network interfaces: WAN, LAN and Sync
Since I have only 2 NICs available on each node. 1 for WAN and 1 LAN.
What's the best way to create the third interface used for sync?
An empty Linux bridge?
