Im new to firewalla.  I want to create a DNS rule to allow to a specific IP and block if it come in from anywhere else.

ALLOW TCP/UDP IN/OUT to 208.67.222.123 or 208.67.220.123 on Port 53

and

BLOCK TCP/UDP IN/OUT all IP addresses on Port 53

 

Thanks in advance

  What you are doing is forcing all DNS to the IP addresses you specified right? if you are, then firewalla already doing this, it will intercept all dns traffic and re-route it to the DNS services you configured. In your case, you can just configure the 208.x.x.x address on the LAN segment.

  Does this also drop DNS coming in from other IP's?
