It sounds to me like the OP may want my filtering bridge patches for
m0n0wall. This lets the servers use their public IP addresses for
everything, no NAT or other addressing hacks required, but they get the
benefit of m0n0wall's "normal" stateful firewall rules.
Basically, apply the filtering bridge patches to m0n0wall, put the
m0n0wall box between the servers' switch and the uplink, bridge the
interface facing the servers with the WAN port, set up firewall rules to
permit whatever desired traffic on the WAN port, and you're done. This
should be totally transparent to the servers.
