Good morning everyone.
I have a fresh install of Proxmox 6.1 (ISO-INstaller)
How do I add a private IP (192.168.22.32) to the host-node to reach a backup-server?
I understand that I am not supposed to touch the interfaces-file manually. I tried adding another bridge in the GUI, but that didn't work.

Thank you for any help!

Current interfaces:

auto lo
iface lo inet loopback

I think I got it solved. I hope I did it right, but its working for now.
