transparent port/ip forward

[michal krajcirovic <konf@krajcirovic.cz>]

hello,
I have server which has several IP. there come requests for port 80 and 
i want this forward requests to other server, where web is running. I 
need that but completely transparent - in the logs on the destination 
server where the webs must be running as well as to direct the opening 
page. Then the real visitor IP, the browser, ...

solutions via rinetd there is now is quite poor, because in logs (and 
stats) are the only ip forward server.

Any ideas on solutions? maybe some squid / apache + proxy / nginx 
forward on the server?

thanks

m.
