Blocking DNS requests

Blocking DNS requests   21 September 2010, 17:02

I want to force people on my LAN to use my DNS located on the same server as BWM.
I want to be able to block any requests to DNS servers on the internet from my LAN but not block my own DNS servers requests to & from the internet.

I have tried all sorts of rules for blocking port 53 but nothing seem to work.

My setup is - Modem/router >>> (server running BWM in bridge mode with DNS server) >>> Network

This must be easy to do. Can anyone help?

Perhaps it can be done with two rules.
The first one explicitly allowing DNS requests to the server say 192.168.1.1 on port 53 TCP/UDP
After that a block rule for all other requests on that port 53.
Have never tried it, others may have a more detailed solution.

Cheers!
