[squid-users] Linux 2.4.18, squid 2.4.S3, IOS 12.2(5) wccp help!

Hi

I may be blind but I can't see the problem.

The problem I am having is that squid works when manualy configured but send
errors when attempting to access a site transparently.

Here is all the info I could think of :

--------

router version

IOS (tm) 3600 Software (C3640-IS-M), Version 12.2(5), RELEASE SOFTWARE (fc1)

--------

ip wccp version 1

interface FastEthernet0/0
  ip address 206.75.213.1 255.255.255.0
  ip route-cache same-interface

interface FastEthernet1/0
  ip wccp web-cache redirect out

access-list 162 permit ip host 206.75.213.195 any
