http://wiki.squid-cache.org/ConfigExamples/#Interception may give you some 
useful guidelines, depending on what your equipment is.

Alternatively you could do policy routing on the "Core Router", giving the 
internal IP address of the Squid server as the gateway for HTTP/S traffic, and 
then you do the standard Intercept NAT on the Squid machine so that it gets 
processed.

http://wiki.squid-cache.org/ConfigExamples/Intercept/LinuxRedirect

Squid then has the "Internet Router" as its gateway to the outside.

The important thing is *not* to do any Destination NAT on traffic to try to get 
it to hit the Squid box.  The destination IPs of the packets must remain 
unchanged (ie: wherever they were trying to get to on the Internet).
