Cisco WCCP Squid Transparent Proxy

Hi Tim,

WCCP is pretty confusing, this tutorial took me about 6 hours from start to finish. I had a lot of troubleshooting to do before this worked…

Your config looks OK and you can see the router is redirecting traffic:

Redirected Packets:
Process: 0
CEF: 929

You don’t have to worry about tunnel source and ip unnumbered for the WCCP configuration. When you configure a “normal” GRE tunnel between two routers you have to specify the source + destination of the tunnel yourself, now we don’t have to because WCCP does this for us.

Ip unnumbered is about the IP address on the tunnel itself, here’s an example if you are interested:

The Cisco side looks OK…what about squid? are you 100% sure it is operational?
