I´m becoming of thinking in throwing the towell......... ive tried several ways of making wccp2 work with my squid 2.6 unstable kernel 2.6 with gre the idea was simple router + switch + clients and squid ive tried it in centos and also on debian (my favourite) all flavours of kernels and squids unstables releases im very close, but can handle it ive setup a gre tunnel with a 10.10.10.1 (router outcoming interface is a 200.x.x.x, ive setup no incoming, E0/0 is a 192.x.x.x class, wccp v2) clients are not surfing but they do if i force a proxy direction on the explorer packets are coming in the gre tunnel, i am seing them with the tcpdump command packets are supposed to be redirected through my iptables to port 3128 (ive tried dnat, redirecting) squid conf is ok, 3128 transparent
