      I added OpenDNS to my pfSense / SG-3100 gateway software a while back. Worked very well for months. Today I needed to restart the box and when I did my WAN connection when 'Offline, Packet loss'. Could not seem to get past the problem (still a noob at this...) so I fell back to an earlier backup that did not include OpenDNS and everything came back up.

      What I am thinking is that because I was using the OpenDNS DNS addresses and not CenturyLinks' DNS my box could not connect back up to the CenturyLink ONT. (ONT is IPOE and I connect directly / no double NAT box in-between)

      Anyone have any thoughts on this. Lesson learned going forward is that if I make a big change always restart the gateway afterwards to make sure all is still good.

        Very unlikely. DNS would not be required to get connectivity. Some thing else was probably different i9n the older config.

          @stephenw10 I was running pfFBlockerNg at the same time with OpenDNS. Not sure that was good idea. Maybe that had something to do with it?

            Unlikely to be an issue. I have something similar configured here.
            If you are also running ramdisks you might see a warning about unpopulated aliases from pfBlocker at boot but they will populate the first time it updates.

            How did you have OpenDNS setup?

            How are you using pfBlocker, just IP lists or with DNS-BL?

              @stephenw10 Not remembering how I had OpenDNS set up. I am only running pfBlockerNG. I have both IP and DNS-BL set up. Also no RAM Disks set up.

              Was in a hurry to get back online for my job. So after a few hours I gave up trying to figure it out and just fell back.

              Probably just chalk it up as an unknown. You have answered my questions. Maybe another time I will try OpenDNS. But afterwards I will reboot to make sure it holds.
