Does the webserver have the debian machine set as its default gateway? This is 
necessary beacause the forwarded connections must pass back through the 
debian box. One way to achieve this is by rewriting the source addresses as 
well, with an SNAT rule, although this will reduce the usefulness of your 
webserver logs.

Another way to do this, that can be quite quickly put in place, is to run 
Apache with a virtual host configuration that acts as a reverse proxy (using 
Rewrite rules).
