The error on the Cisco router is stating that the squid box is trying to tell the router that it is able to service the wccp group 80 and 90, but for some reason the router does not see those groups as ones it is servicing. This is odd. Try doing the following in the router: ip access-list 180 permit any any ip wccp web-cache redirect-list 180 ip wccp 80 redirect-list 180 ip wccp 90 redirect-list 180 Is the squid box on the same router interface as the rest of the clients? If it is, you may need to add lines to the access-list 180, or put the squid box on the secondary interface of the router and do a "ip wccp redirect exclude in" statement on that interface. Which IOS feature set and version is this? WCCP is buggy in some IOS releases. ________________________________ From: R_O_L_A_N_D@xxxxxxxxxxx [mailto:R_O_L_A_N_D@xxxxxxxxxxx] Sent: Mon 1/5/2009 8:43 AM To: squid@xxxxxxxxxxx Cc: squid-users@xxxxxxxxxxxxxxx Subject: Re: transparent proxy not working!! any advice? Hello, actually I have both of set on the lan interface ( am I mistaken to set the "redirect out" on the lan interface? should I be setting it on the interface facing the internet?) ip wccp 80 redirect in ip wccp 90 redirect out as for the wiki provided, I fail to see what's missing! obviously there is something, but I'm not detecting it! --------------------------------------------------
