why vhost and vport=80? These are for accelerator/reverse proxy mode,
not Internet proxies.. The transparent keyword takes care of all which
is needed in transparent interception.

I would say it's better to create a new GRE tunnel for the router.

ip tunnel add wccp mode gre remote ip.of.router
ip addr add proxy.server.ip/32 dev wccp
ip link set wccp up

and intercepted packets redirected by the router should be coming in on
the virtual wccp interface, where they can easily be redirected to Squid

iptables -t nat -A PREROUTING -i wccp -p tcp -j REDIRECT --to 3128

You quite likely also need to disable reverse-path lookups on the wccp
interface

echo 0 >/proc/sys/net/ipv4/conf/wccp/rp_filter 


IP forwarding does not need to be enabled.
