It’s always better to keep the port closed if possible. So better use VPN.

I don’t use VPN in that case but I opened the port only for specific source IP addresses (so only addresses of my Nodes). All other Source IPs are blocked by Firewall.
Maybe it will give you some idea.

Best regards

Ok so rather than letting the router perform the allow-list, you told the PVE firewall to perform this? I think I will simply let my router's firewall perform this.

Thanks Floh,

No, I have a dedicated machine as firewall (OPNsense) and Proxmox Backup Server is running as VM on my QNAP.

Oh nice, I just setup two OPNSense routers, so much higher performance, even on weak old xeons! Why spend thousands on something with 1-4GB of RAM and a few ARM CPU cores when you can build a better version for a couple hundred? :p
