There are a number of possible approaches.  On the router side, all of it
is easy ("ip route 10.10.1.0 255.255.255.0 <someconnectedhost>").

The interesting part is the server side - you can do alias interfaces, or
transparent proxying (for example via squid), and so on.  Depends on the 
operating system used and whatever experience you have with the possible
web server / web proxy variants you have.
