Firewalling setting on proxmox - on or off?
Post Body
Seeing differing advice on this as far as it's concerned for opnsense. From what I can tell it's just if you want a firewall before data even hits the hypervisor, IE before opnsense.
I assume I'd only need it turned on for the WAN port, but do I need it at all? I'm still learning opnsense itself, so curious if I want the headache of another firewall on top of this one. Or is it as simple as just putting a rule for accepting anything outward and blocking anything inward?
