Configure Proxmox's pveproxy to listen on localhost only

TL;DR: Read the man page man pveproxy

Put the following in /etc/default/pveproxy (it needs to be created if not already existing).


Then restart pveproxy.service.

That's it.

Oh it's also mentioned in the manpage but it's worth reiterating, tweaking this setting after setting up a cluster is asking for an issue, the cluster normally communicates directly on 8006.

This could break something pretty major so uh, not my fault.
