Thanks for the tips. I just migrated the pfsense. Great idea!

I am lost. What do you use the third nic for? Do you use it to replicate pfsense or proxmox configurations? If you migrate pfsense vm when necessary, you don’t need to replicate its configurations. I must be missing something.

Nice. I’ll try that myself. Any tips you could share? I assume you have to use the same bridge name for the two interfaces on the two promox nodes for the seemless migration.
