multiple webservers one gateway?

How can I put multiple server machines behind a single gateway? That is how can I forward port 80 to more than one internal ip address?
##scratching my head??

Simply put, you can't. For any given combination of EXTERNAL IP and port, only one service may respond to that. Your gateway has no way of knowing which of the webservers to forward the request onto. Perhaps there's some sort of proxy system that would allow the gateway to act as a webproxy and forward on based on hostname, but I'm not sure.

Really depends on what you're trying to achieve. Are you trying to get load balancing between multiple web servers? Or what? How many public IPs do you have?

No its a matter of housekeeping. Two lotus notes server machines with dedicated support team need to sit along side an apache machine the house looks after.

Well, if they need to use the same port numbers on the outside, then they need distinct world-routable IP addresses.
