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

Hi Adam,

We have such an installation and Proxmox works fine, given the 
limitations of the underlying hardware (most notable are the disks).

For the firewall you can use a dedicated VM or also the native proxmox 
(hypervisor kernel) iptables. We use iptables on the hypervisor, managed 
by the Firewall Builder front-end, and are quite happy with it.

Hope this helps,
Eneko
