Allowed Applications
Click or touch applications you wish to give access to the internet
while the Port Filtering feature is enabled. All other applications
will be blocked.
Note: DNS (Domain Name Server) should always be enabled when using Port
Filtering. Without DNS, it is not possible to convert a Domain name (for
example, www.msn.com) to an IP address. DNS is used by E-mail, FTP,
and many other protocols as well as by Web browsers.
