Blocking DNS queries With IP Range.

[amk]

Hello,

Need some help I need to block dns queries using OpenDns.

I have managed to setup OpenDns and test and it works.

What I want is to block a IP range from 192.168.0.20 to 192.168.0.254. Tried Multiple formats and failed.

Regards,

Amk.

That is not how you would block it.

Create an alias to include that subset of your network.

That's not how it works.  When Destination is a network, you must supply the network address and CIDR mask eg. 192.168.0.0/24.  You can't put a range there.  Using 192.168.0.0/27 gives you 192.168.0.1 - 192.168.0.30 usable so use that instead and modify your network allocation, or you could also do 192.168.0.0/28 which gives you 192.168.0.1 - 192.168.0.14 usable.  Check the Invert Match box and it should work for you.
