The REDIRECT target is valid only for the local machine. You have to use
the DNAT target, like Alexander Dalloz suggests, except that you dont't 
have to bother about udp: http is a tcp-only protocol.

There are a lot of other things to take care of: routes, name-resolving, 
allowing access with NAT from the squid machine to the internet and 
maybe something else that I can't think of now.
