You can also input a web filter file name here. The web filter file format is one web filter for one line. For example:

.yahoo.com;

.hotmail.com;

  • Forbidden Sites: the clients can not access the sites which are included in the site filters.
  • Advanced DNS Filter: Input the OpenDNS address here.
  • Forbidden URL: You can define the URL filter here. You can input whole or partial URLs. For example:

http://www.google.com/;.zip;.exe;/mail/;
