URL Filtering Configuration
URL Filtering Overview
The Uniform Resource Locator (URL) filtering function is used to filter HTTP requests. URL filtering
includes user-defined URL filtering and category-based URL filtering.
z User-defined URL filtering: Allows you to specify the matching criteria for a domain name and
Uniform Resource Identifier (URI) path, and configure the corresponding actions on the device.
z Category-based URL filtering: Refers to the process in which the device, upon receiving an HTTP
request, sends a URL category request to the specified URL category server, obtains the category
result, and processes the HTTP request based on predefined category-based URL filtering rules.
The device does not support category-based URL filtering.

by selecting System Management > Network Management > Segment

certain IP addresses in the internal zone. The IP addresses and excluded IP
addresses are configured for the internal zone.
