No. The traffic being redirected via WCCPv2 just rewrites the next hop
in the forwarding path; making it go down a GRE tunnel or rewriting the
destination MAC address.

The packet arriving at your cache still has the original source/destination.
iptables/etc is needed to redirect packets destined for ANYHOST:80 to
LOCALHOST:3128 .
