Using Simple DNS Plus with Norton 360 / Internet Security

Norton 360 / Internet Security are products from Symantec - http://www.symantec.com

The "Personal Firewall" in Norton 360 / Internet Security monitors network traffic by application / program.

By default it is configured to "Automatically decide what to do" when programs attempt to communicate with the Internet.
With this default setting, it should automatically allow Simple DNS Plus to communicate freely.

If however you have this setting set to "Ask me what to do":

Just accept the default "Allow always" and click the "OK" button.
