      Hi guys!

      Since a couple of weeks, I noticed some weired logs from my pfsense 2.0.3. They always block various IP's of my ISP's DNS servers I'm using. As you can see, destination is my pfsense IP but different ports.
      Why is this happening? Any answers, or soloutions for me?

        I would assume those are answers to your dns queries.. BTW At a loss to understand why you should block out the IP of isp dns?

        They shouldn't be blocked since you should have connection tracking of your query to them, etc.

        I would sniff the traffic and see what is in there if it was me - is dns working?  Is it constant or does it come and go in bursts as you surf?  Running p2p can generate large amount of dns queries.
