So you have one real IP on the firewall box and virtual IP's that are
directly routed to the real box's private IP.
"iptables -t NAT -I PREROUTING -d <public IP> -j DNAT --to-destination
<private IP>"
There will be no filtering at all on this.
Then add a back route:
"iptables -t nat -I POSTROUTING -s <private IP> -j SNAT --to-source
<public IP>"
It would be good to modify those rules by making a series of tables that
filters out the crap before just routing all the bandwidth to the work
machines.
