Yes, I think it would work to have a firewall VM with the public IP, 
configured as HA; then nodes have private IPs.

Administration would be by VPN as Alain said. If the node running the 
firewall crashes, HA would restart it on another node. VMs gateway would 
be the firewall.

You need shared storage for this of course.
