What port forwarding is required when Proxmox Back Server is behind a firewall?
Which network ports are required

Wow, this is really impressive Tom. Is there guidance for remote installations? Should there be a VPN connection or do you think that allow-listing the source would protect it enough while port forwarding?
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,

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?
