      this is getting to be crap….i am having to reboot every couple of hours...resolution just completely drops.

      everything is set to default now, and its going tits up still.

      the only thing i see in the logs is when it updates dyndns ...which it shouldnt. there is not even a package installed on this box.

        The DynDNS reference is there just from a script that notes if your WAN IP has changed in case you are using DynDNS. I don't think it's relevant here.

        So the problem you're having is that the pfSense box loses DNS resolution and is only fixed by rebooting?
        Your clients on LAN, using different DNS servers directly, still have DNS?

          well i found that the interface keep going up and down every two seconds. i am installing 2.1.3 release (amd64) from scratch (instead of upgrading) to see if that fixes the issue. one issue i believe that may have been a problem was using ultradns servers .. so i will be using a different set of dns servers (not sure if i will use opendns or not…i like dns servers that filter crap out, but do not track like google public dns servers)

          it all came down to dns resolution and that particular interface (which i think was a little bunk'd)

          ill update results soon.

            I think im having the same problem.  after a few hours to a day, the wan becomes very very slow. cpu and memory are very low.  a reboot resolves the issue.  I upgraded from 2.1.2 to 2.1.3.  My next step may be a fresh install too.

            Did a clean install resolve your issue?

              How are you testing that WAN becomes slow? What are the symptoms?

              Probably not related to this post so better to start your own thread.

                I think i my issue has been resolved by  disabling hardware checksum offload.  Strange that I didn't have this issue with 2.1.2.  Did the intel nic drivers change in the new release?  I'm going to continue to monitor this, and I'll start a new thread if the issue returns.

                  As far as I know the drivers were updated between 2.1 and 2.1.1. not more recently.
                  2.1.2 and 2.1.3 were mostly security patches.

                    Hi,

                    I experience the same problem.

                    Here is a description :

                    • 2.0.3 rock stable configuration, 6 month uptime without care of firewall etc.
                    • Upgrade from interface to 2.1.3 yesterday, few minutes after first boot lost WAN interface, red cross on the status page.
                    • Rebooting solved the problem for a couple of minutes.
                    • This morning WAN interface was down, PPPOE was "UP" in the status (witch seems weird without WAN up).
                    • As said before by Speedy3k, I have checked "disabling hardware checksum offload" and it seems to solve the problem.

                    As this was done 1 hour ago only, I'll post the result of the "disabling hardware checksum offload" in a few hours.

                    I use a PfSense 32 bits release, on an Intel Celeron NUC box with a proven working USB WAN interface in 2.0.3 release (my internet connection is 7MB so it's enough).

                    How can we help developers to solve this issue ? Can you please advice me logs & traces to upload here ?
                    It's a home firewall, I can play with it

                    Cheers,

                    Phil

                      I've been participating in a thread over in OpenVPN :https://forum.pfsense.org/index.php?topic=76735.0

                      They seem to have uncovered a small bug which may inadvertantly trigger WAN address resets as if the associated gateway has dropped out (typo in /etc/newwanip).

                      It might have nothing to do with your issues, but it's a simple fix and it might be worth a try to see if it helps.

                        Very interesting : I have a poor ADSL line, with a simple 768kb upload link and loooootsa latency issues, because it is always overloaded !

                        I'll do some tests this evening when I'll be back at home, even if the previous fix seems to work : I don't have loose the WAN interface yet, my port-fowarded server always UP.

                        Thanks for pointing this subject.

                          For the  gateway monitoring I have setup 750ms/950ms and it seems to be stable since a few hours.

                          And I have setup back the hardware stuff, because of the rules "one mod only at a time  :)".

                          More to come later …
