AFAIK it is not possible to distribute the traffic between two NATted
webservers with the same outside address/port using IPtables. If they will
have different addresses visible from outside then it's a dawdle.

If they have different *names* then you could setup a reverse proxy on the
firewall device (e.g. squid).

What are you trying to do - run different stuff on the webservers or
load-balance?
