Figure 48 The URL Filter Screen
To enable the URL Filtering, please do the following:
1 Check the Enable URL Filtering Function box to enable the URL
filtering.
2 Enter the URL or key words of the URL in the text field for your desired
website.
To filter a specific site, enter the URL for that site. For example, to stop
your users from browsing a site called www.badsite.com, enter
www.badsite.com or badsite.com in one of the fields.
If badsite.com has multiple sub-domains, such as this.badsite.com and
that.badsite.com then you can either:
Block them individually by entering this.badsite.com in one field
and that.badsite.com in another.
or
Block them by entering the keyword badsite.com into one of the
fields. This will block all URLs containing the string badsite.com. As
well as blocking this.badsite.com and that.badsite.com, the
keyword badsite.com would block searches that mentioned
badsite.com in their domain name, for example
www.notabadsite.com.
