How to setup WCCP on a Cisco ASA Firewall in 3 commands

########
# Setup WCCP version 2 on Cisco ASA firewall to a Web Filter (192.168.42.42)
#
#
# Create Access List called “wccpserver” for Web Filter
#
access-list wccpserver extended permit ip host 192.168.42.42 any

#
# Setup wccp v2 with no passwords,
# assumes all web traffic hitting internal interface will be rerouted
#
wccp web-cache group-list wccpserver
wccp interface inside web-cache redirect in
#
#########

And done. There are more WCCP option, but this should get you started.

Cisco’s documentation on WCCP (that fails to explain access lists) can be found here: http://www.cisco.com/en/US/docs/security/asa/asa72/configuration/guide/dhcp.html#wp1094445

I am a security tech in the field.  I install firewalls, anti-spam, anti-virus, web content filtering any many other products.  I also like to tinker with my Linux and BSD servers.  The Internet is chock full of information, too bad a lot of it is not what I’m looking for.  I hope some of the information I post helps somebody along the way.  Comments, thank yous and corrections are greatly appreciated.
