Url Filter - Asus DSL-AC52U User Manual

4.6.2 URL Filter

You can specify keywords or web addresses to prevent access to
specific URLs.
NOTE: The URL Filter is based on a DNS query. If a network client has
already accessed a website such as http://www.abcxxx.com, then the
website will not be blocked (a DNS cache in the system stores previously
visited websites). To resolve this issue, clear the DNS cache before
setting up the URL Filter.
To set up a URL filter:
1. From the navigation panel, go to Advanced Settings >
Firewall > URL Filter tab.
2. On the Enable URL Filter field, select Enabled.
3. Enter a URL and click the button.
4. Click Apply.
