keywords for blocking and designate a trusted computer.
14.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Content Filtering Profiles
Content filtering allows you to block certain web features, such as cookies, and/or
block access to specific web sites. For example, you can configure one policy that
blocks John Doe

A content filtering profile conveniently stores your custom settings for the
following features.
Keyword Blocking URL Checking
The NBG4115 checks the URL ’ s domain name (or IP address) and file path
separately when performing keyword blocking.
The URL ’ s domain name or IP address is the characters that come before the first
slash in the URL. For example, with the URL www.zyxel.com.tw/news/
pressroom.php , the domain name is www.zyxel.com.tw .
