Cisco ASA WCCP bypassing when going to certain websites
Posted on 2012-12-28
I am running WCCP on a Cisco ASA5510 firmware 8.2.(1)11
My current configuration for WCCP is:
access-list wccp-server extended permit ip host 192.168.0.121 any
access-list wccp-traffic extended permit ip 192.168.0.0 255.255.255.0 any
wccp web-cache redirect-list wccp-traffic group-list wccp-server
wccp 70 redirect-list wccp-traffic group-list wccp-server
wccp interface inside web-cache redirect in
wccp interface inside 70 redirect in
I am running a Sophos web appliance on IP 192.168.0.121. We're having issues with a particular website that runs a Java app that is being blocked by Sophos. Sophos support has recommended that we modify the rule on the WCCP and bypass traffic to 209.223.80.74 and 209.223.80.73 on the Cisco from WCCP.
I have never created any exceptions like this before and would like some advice on how to configure this.
Thanks

You should just need to add a couple deny statements above the permit on acl wccp-traffic. In the end the acl will look like:
access-list wccp-traffic extended deny ip 192.168.0.0 255.255.255.0 host 209.223.80.74
access-list wccp-traffic extended deny ip 192.168.0.0 255.255.255.0 host 209.223.80.73
access-list wccp-traffic extended permit ip 192.168.0.0 255.255.255.0 any
This will effectively deny traffic destined to those IP's from being redirected, but permit everything else to be redirected.
