Which kernel versions? The WCCP support in ip_gre is fairly recent (2.6.9 or something like that). And make sure you follow the instructions in the FAQ on how to set up the tunnel. There is a number of things which need to get right for it to work.. http://wiki.squid-cache.org/SquidFaq/InterceptionProxy#head-a7fed84c39e23407b93737da0815d1e6ed926a4f > What protocol does ip_wccp use? WCCP(1&v2)/GRE, nothing else. Any other GRE packets is dropped on the floor. > Does it setup it's own GRE thing? ip_wccp is a WCCP-only GRE implementation, blindly decapsulating WCCP/GRE packets with no checks of any kind, making it look like the encapsulated IP packet was received on the receiving network interface without encapsulation. It can only be built as a module, and as soon as it's loaded in the kernel it starts doing it's job on every GRE packet received on any interface, from anyone to any configured IP address. ip_gre is a full blown GRE implementation, and supports WCCP since quite some time back. See the Squid FAQ for configuration instructions as there is a number of small things to configure to make it work for WCCP. Regards Henrik
