Virtual to physical

[m3freak]

Could I successfully build out an opnsense firewall as a KVM, back up the config (using opnsense's built-in backup feature), install opnsense on physical hardware and then restore the backup to the new physical box? I don't see why it wouldn't work, but I haven't used opnsense before so I don't know if I'm expecting too much.

The interfaces will probably named differently. The renaming can also occur when moving from one hardware to another.

You can modify the interface names in the config.xml before restoring it on the target, or tweak them afterwards, paying attention to the correct order of interfaces (opt1...optN)
