[PVE-User] Interested in running Proxmox on a single (for now) colo node

Well, maybe I'll setup Proxmox on a system here or in a VM and try working
with host firewalling and see how I like it and then try pfSense. After
thinking about it for a bit I may just go with pfSense in a VM. It's not
like I'm going to be loading this system much as it is and a little VM
running pfSense isn't going to exactly break the bank CPU or memory wise.
Plus, like I mentioned before I'm more familiar with it and as you eluded
to it includes OpenVPN support that's easy as hell to configure.
