Kumar, Thanks for the info. These are the commands I have been using to try to get this working, but have not been successful. I rebooted the box and started the network config from scratch copying and pasting your commands, replacing the appropriate values of course. But still on the cisco router I get the same info from the "show ip wccp web-cache detail" command. When I do a packet capture, I can see that the router hands the cache server all the buckets, but when the cache server replies it shows all buckets as unassigned. Also, with this command in iptables, should I not be able to telnet to port 80 on the box and be redirected to port 3128? When I try this "telnet localhost 80" I get a connection refused.

I am sure this is a problem with my gre tunnel (if I even need one) and my firewall configuration. Can someone send me their firewall and gre tunnel config? > >Thanks, >Bryan > > > > >
