15.1.2What You Need to Know About Filtering

IP/MAC Filter Structure

An IP/MAC filter set consists of one or more filter rules. The P-660RU-Tx allows you to configure up to twelve filter sets with six rules in each set, for a total of 72 filter rules in the system.

URL

The URL (Uniform Resource Locator) identifies and helps locates resources on a network. On the Internet the URL is the web address that you type in the address bar of your Internet browser, for example “http://www.zyxel.com”.
