OpenVPN as server management with PXE boot

onerealkewlguy

I am looking at installing many small pxe booted servers at many locations. Each location/server would be independent of the others though centrally managed by one or more workstations. Each location/server would have dual NICs with one for PXE boot and the management/control through a vpn and the other NIC for public internet for the location.

What OpenVPN products would I need to buy to manage this scenario?

I expect to cloud host the vpn and I wonder if I would need seperate instances or one large instance of openvpn servers for connecting each location? I'm guessing that I would need to use bridged networking for the dhcp broadcast to boot pxe.

Could I just place an initial host OS on each box and configure the client to call the vpn connection upon power up while being connected to the internet?

I did find a post on another board that discusses how someone got a pxe boot through vpn working by using dnsmasq. Can anyone put me in touch with a consultant that could set this up for me using OpenVpn?
