    Good morning to all,

    speedtest.net don't work anymore in my pfsense install.

    I disable this commit in my pfsense :
    https://github.com/pfsense/pfsense/commit/7d8b75ab01103a24ee5de63130065de8d5b3e9b4

    and now works normal.

    Is really necessary disable udp checksums ?. Will other services like openvpn udp tunnel be affected ?.

      How that impacts the speed test?
      Normally very few services require udp checksums hence the disabling.

      Maybe speed test enforces it by i am not sure on that.

        The page not work. A connecting message is displayed in browser bar.
        I think speed test use this in some way.

          I had some questions about this change too. Why this is implemented and shouldn't it be in "System: Advanced: System Tunables"? I never see an advice to turn this off when googling for it. On the other hand Ermal is supposed to know what he is doing.

          However:

          [2.1-BETA1]:sysctl net.inet.udp.checksum
          net.inet.udp.checksum: 1
          
          

          So it is not disabled…

            What is the rationale behind the change of this kernel tunable from the FreeBSD default ?

              I reverted to old behaviour and made this a system tunable.
