You need to setup NAT on the router between the host and the internet. eg: forward port xyz to port xyz on whatever internal machine.

If memory serves me something like this (as root):

Code:
iptables -t nat -A PREROUTING -p tcp -i eth0 -d xxx.xxx.xxx.198 --dport 80 -j DNAT --to 192.168.5.184:80
iptables -A FORWARD -p tcp -i eth0 -d 192.168.5.184 --dport 80 -j ACCEPT
