Can you post a squid -v?

I've been running squid-2.6 and squid-3 with wccpv2 and it works fine.
The thing I initially forgot was --enable-linux-netfilter.
It'll run; it just won't work. :)

Have you bought up a 'fake' gre interface just so the kernel will
handle incoming GRE?

also, have you turned on ip forwarding and turned off rp_filter ?
