WCCP on ASA question

Answered Question
Sep 30th, 2008

Hi All

I am trying to configure WCCP on the ASA, it seems pretty straight forward but I am not having any luck with it working.

The Web cache server we are using is the Barracuda Web Filter with the latest firmware update that is suppose to work with WCCP V2.

So this is what I have and did.

I have the proxy server in the company DMZ, I created a ACL that allows all IP traffic from our Guest net to go to the IP address of the proxy in the DMZ. I then configured the webcache to use this ACL and added the service to the redirect group.

After this it still does not use the Barracuda server. The one thing that I was thinking may be the issue, it is mentioned in the docs that the proxy and the clients accessing the proxy have to be on the same interface, which they are not. The clients can access the server no problem but they are not on the same interface. Anyone know if this is the issue or does it work when the proxy is on the DMZ interface and the clients are on the internal interface?

I have this problem too.

The only topology that the security appliance supports is when client and cache engine are behind the same interface of the security appliance and the cache engine can directly communicate with the

client without going through the security appliance.

I was afraid of that:( I was hoping I read it wrong or there was a change so I did not have to redesign the current network to get it to work..
