WCCP v1 Cisco with cache on separate interface

Hello all.

My Cisco router has 3 interfaces. Fe0/0 is the incoming interface with all the web traffic from the clients. Fe0/1 is connected to the internet backhaul and Fe0/2 connects to the cache engine farm.

I enabled wccpv1 (since my cache supports only that) on the cisco router and configured the ip wccp redirect out command in the Fe0/1 interface which is the path to the internet.

I see that the response(I_See_You) from the cisco to the Here_I_Am messages from the cache server uses the source interface of Fe0/2 (since that is the closest interface to the cache farm LAN, I suppose). !!!

Doing an show ip wccp web-cache detail shows the WebCache ID as

Interestingly redirection is occuring on the cisco router when I try to browse (as indicated by the counters in the same command) but it is not working... is this because the gre tunnel is using a source interface of 0.0.0.0 ???

ANy ideas on how I can get the router to use the correct webcache ip address??

thanks,
