12.6 Customizing Keyword Blocking URL Checking

You can use commands to set how much of a website’s URL the content filter is to check for keyword blocking. See the appendices for information on how to access and use the command interpreter.

12.6.1 Domain Name or IP Address URL Checking

By default, the ZyXEL Device checks the URL’s domain name or IP address when performing keyword blocking.

This means that the ZyXEL Device checks the characters that come before the first slash in the URL.

For example, with the URL www.zyxel.com.tw/news/pressroom.php, content filtering only searches for keywords within www.zyxel.com.tw.

12.6.2 Full Path URL Checking

Full path URL checking has the ZyXEL Device check the characters that come before the last slash in the URL.

For example, with the URL www.zyxel.com.tw/news/pressroom.php, full path URL checking searches for keywords within www.zyxel.com.tw/news/.

Use the ip urlfilter customize actionFlags 6 [disable enable] command to extend (or not extend) the keyword blocking search to include the URL's full path.

12.6.3 File Name URL Checking

Filename URL checking has the ZyXEL Device check all of the characters in the URL.
