[7.921][QUESTION][OPEN] PacketFilter drop dns from Internet ip??

I have close to 10000 DNS packet dropped per day, but they seem to come from my internet IP to go on the internet.... Which I don't understand..

I have rules set to allow my local network to do DNS to any network.

My cable modem is connected to ETH0

I get theses: The source is always my Internet IP, and the dest seem to be a set of about 20 that repeat over and over. I found my ISP's dns server in the set...

My internet work fine and resolve well.  And if I got on astaro inside tools, I am also able to resolve DNS there...

Anyone have an idea?

    It may mean nothing but has anyone noticed that these are all Root Server addresses in x-cimo's log?
