I have this set up using the ip_gre module. I didn't do anything to patch it. How do I do that? I managed to find a patch for ip_gre at swelltech but don't have a clue as to how to apply it.
The way I understand it all, the router intercepts the port 80 traffic and forwards it to the proxy via WCCP. The proxy receives the traffic via the ip_gre module where it is grabbed by iptables and redirected to the port that the proxy is listening on. Then the proxy does its business and sends the return traffic to the client via regular traffic and not back through the gre tunnel. Is this correct? Okay, now the big question. Is there an easier method of transparent proxying. LOL.

I think you just set up a gre interterface with the router as endpoint. Then the patch takes over. This GRE should only be used for receiving traffic from the router, not for return traffic. > And once that is done, then I have to enable port redirection?

It is the responsibility of the proxy server box to intercept the traffic and redirect it to the proxy application. Regards Henrik
