DESCRIPTION
Select this check box and the Zyxel Device will not reply with a DNS reply packet
containing a default or custom-defined IP address when a DNS query packet contains an
FQDN in the white list.
Click this to create a new entry. To add an FQDN, type a Fully-Qualified Domain Name
(FQDN) of a web site. An FQDN starts with a host name and continues all the way up to
the top-level domain name. For example, www.zyxel.com.tw is a fully qualified domain
name, where "www" is the host, "zyxel" is the third-level domain, "com" is the second-
level domain, and "tw" is the top level domain. Underscores are not allowed. Use "*." as a
prefix in the FQDN for a wildcard domain name (for example, *.example.com).
Select an entry and click this to be able to modify it.
Select an entry and click this to delete it.
To turn on an entry, select it and click Active.
