iptables and 2 web servers

Hi,

I have two web servers behind the iptables firewall. In W1 web server, it
has a hyperlink pointing to W2 webserver. W1 is the existing web server,
the W2 is under construction. I have no problem redirecting packets from
the linux box to the W1, but I have no idea redirectiong packets to W2,
since both using port 80.
Would any one give me some suggestion? Any help will be appreciated.

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?

Check out (AFAIK) a 2.6.x kernel configuration under Network
Drivers->Network options->IP: Virtual Server Configuration. I think you
might find your answers there. I am currently attempting the same, as I
have the carcass of an old Intel e-Commerce server that originally did
just what you want, with the added twist of having 2 hardware encryption
keys in it. Now, if I can just find drivers for those!
