I would think you could use DNAT:

# iptables -t nat -A PREROUTING -p tcp -d --dport 80 -j DNAT --to-destination

# iptables -t nat -A PREROUTING -p tcp -d --dport 80 -j DNAT --to-destination

is private lan ip from source to destination ( ?

The addresses and port is an example.

When the firewall receives port 80 traffic destined for IP aaa.bbb.ccc.ddd it routes it to IP bbb.ccc.ddd.eee
