In the meantime, you can use something like this (I used this until split
DNS came into play on my network):
$IPTABLES -t nat -A PREROUTING -i internal-interface -d your.external.ip.address -j DNAT --to your.internal.destination.IP
$IPTABLES -t nat -A POSTROUTING -o internal-interface -d -s your.internal.netowrk/netmask -j SNAT --to firewall's.internal.ip.address
