You need something which is going to intercept the outgoing packets
(which the client PC on your site believes it is sending to the off-
site WWW server) and send them on to your proxy (perhaps rewriting the
destination IP address).

This requires a box which sits between your internal clients and the
rest of the world. Whether you class this as a firewall is up to you
(in the sense that if it just diverts packets - is it really a fire-
wall). It is certainly the same sort of thing (matching packets by
rules and rewriting / rejecting them) as a firewall.
