You have enabled Cache Bypass and the Webcache can no longer
connect to the World Wide Web

reside on the same subnet in your network, special settings are required
on the Cisco router to implement the WCCP solution (see
page 324

Configuring the Webcache for Cache Bypass will no longer work in this
configuration. Enabling Cache Bypass on the Webcache will result in a
loss of web connectivity. You should ensure that Cache Bypass is disabled
on the Webcache.
To disable Cache Bypass:

2
Click
Device

You can implement client machine bypass capability using the Cisco
router to perform the bypass. Consult the documentation that
accompanies your Cisco router for further information. See also
“Client
