Custom Filter List

Use the Custom Filter List menu pages to create URL Permit or Block lists consisting of lists of URL

name patterns which can represent domain names, URLs, IP addresses, simple keywords or regular

expressions entered by the administrator. When a user requests a connection to a website, the device

checks the URL address against the addresses included in the Current Permit Patterns and Current

Block Patterns to see if the user is permitted to view the site.

The X family device performs a DNS to IP address conversion before checking the Permit/Block lists.

This enables web sites to be identified by domain or IP address, and prevents the Block List from being

undermined by web requests for its IP address.

Use the Custom Filter List page (Firewall > Web Fi ltering) to configure and manage the Permit and

Block lists. The following figure shows the Custom Filter List page.
