I think I have done it! I had to play with the Syslog tool to see what was happening but got there in the end.

I must say that the Syslog info is not very good in that, as far as I could see, it did not show all relevant information.

under data filter:

1. create a "block if no further match" rule for port 53 to any address

2. create an ALLOW rule for requests on port 53 to 208.67.222.222 & 208.67.220.220

now, when a request comes in on 53 (dns), the router will drop the dns requests if they don't match the 2nd ALLOW rule.



I was looking for an answer on how to do this, thanks!
