      I use emby server to stream video to my TV at home. On the same subnet my latest 80GB video file steams flawlessly.

      However, when the sever is on a different interface (DMZ) via pfsense, there is buffering, which tells me something is not optimized on the pfsense router.

      I've disabled all extra services (suricata, BandwidthD etc)

      The hardware specs are more than adequate
      Intel(R) Core(TM) i3-5005U CPU @ 2.00GHz : 4 CPUs :
      4GB RAM
      b17f44af-8bc7-4eec-88f6-6dac442921ec-image.png

      Interfaces are set to full-duplex 1000baseT
      LAN 1000baseT <full-duplex> 192.168.188.1
      DMZ 1000baseT <full-duplex> 10.10.10.1

      What can I do to inspect this further please?

        @bn1980 You could try an iperf test or FTP transfer between the networks.

        Is there a limiter set up?

        Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
        When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

          @SteveITS - Thank you for your reply.

          iperf to pfsense 94.1Mbits
          iperf to server via DMZ the same.

          I will continue investigating

            No buffering with this turned off!
