Block Specific URL in Juniper Netscreen 5GT

I have successfully configured the Web filter in my Jetscreen 5GT but can only get it to work with the reconfigured categories.  How do I block a specific URL?

I have had the same problem. The Netscreens are really bad at blocking sites by URL or Domain Name. Basically, you need to get the ip address of the website by pinging it. Then go into the WebUI and go to Objects > Addresses > List. Create a new untrust site with that ip address with a /32 bitmask. Then go to policiesand create a policy from trust to untrust. Make the trust side your internal network, the untrust side that ip address you created in the address list. Set the policy to deny and put a check in place this policy at the top. Press ok and test.

That's because they have multiple sites using BGP. You block 1 ip and another one reroutes it through another ip. What you have to do is research them by blocking 1 ip then trace route to them again and block the next ip until none of their ip addresses for the website can be found. This is a long task, but it is the solution. These firewalls are not really ment to be used like this. Try it on another site not using BGP to test it. Like nypl.org. The ip is 65.88.89.108. If you block it, you wont be able to get to the web site.
