Websense is a third-party filtering software that can filter HTTP requests on the basis of the following policies: destination hostname, destination IP address, keywords, and username. The software maintains a URL database of more than 20 million sites organized into more than 60 categories and subcategories.

I have a Cisco CE-565A which can support Websense version 5.5.2 if upgraded with the new Cisco ACNS Version 5.5.7

I need features that are available in Websense version 6. Is there a Cisco appliance that can support this.

I am not sure if a new Cisco product is compatible with the latest Websense 6.3.1, I will check.

What does your filter statement look like? Do you have the allow statement at the end? For example filter url http 0 0 0 0 allow. If you do not have the allow statement, when the firewall can not communicate with the websense server url access will be denied. I noticed you have a lot of stat counts. You may want to consider clearing the stats from config mode (clear url-server stat). Monitor the any increases in the deny counts to see if any traffic is actively being dropped.

Thank you for the information. I do not see anything obvious. Do you have the syslog messages indicating the URLs were denied? I was reading the command reference. When configuring the firewall add the url-server first followed by the filter commands. I am not sure of the impact if you reverse the order. Maybe traffic is denied (who knows). Finally, what version of OS are you running. I know that early 7.x code had a number of issues with Websense. Have you looked at the bug tool kit to see if your OS version has any related Websense bugs?
