I'm seeing some strange behavior with our new ASA 5545-X with the Sourefire URL filtering.
I'm intermittently able to get to known bad sites that should be blocked. For example, we are testing the porn URL filtering and our device is configured to NOT allow any Nudity. For some time, I'm able to browse playboy.com or some of the other known bad sites. Then, without any configuration changes, the sites get blocked. It also seems that after an undetermined amount of time, the sites are allowed, at least for the first attempt then they are blocked again - sending users to the block page.
Also, a few sites (well known Adult sites) are allowed when, clearly, they should be blocked.
Is anyone seeing anything like this?
