You need to make a transperant proxy.  If you're router was linux,
you'd use iptables to redirect the traffic to the proxy.  Then the
proxy  would make the connection out to the internet.

Instead of squid you would use your proxy:

I doubt you can do this with a linksys router.  I also don't know of
any windows tools for doing this.
