      Hello!

      I'm running pfSense+ (FW 23.05, Netgate 6100 Hardware) behind a Zyxel AX7501-B0 XGS-PON ONT on a fibre-network.
      It's a synchron 10Gbit/s connection while around 8.8 Gbit/s are promissed to achieve.

      I'm doing speedtests with my Laptop which has a 2.5 GbE connection.
      The speedtest does 2.3 Gbit/s download fine.
      But the uploads are only at max. 200 Mbit/s.

      When I connect the original Fibre-Router of my ISP to the pfSense I get synchronous 2.3 Gbit/s in both directions. But as soon as I connect the Zyxel I get only the 200 Mbit/s upload.

      I cannot/don't want to use the original router of my ISP because it doesn't support a bridge-mode and I would have a double NAT on my WAN.

      In the Netgate 6100 I use a Mikrotik S+RJ10 SFP+ module for getting the WAN-speed that I want to. I know it's not officially supported but as I wrote before: It works fine in combination with the original ISP router.

      Traffic shaper has been used in the past but got completely removed from all interfaces.

      Status > Interfaces shows 0 In/out errors on the WAN interface.

      Thank you in advance for your help and best regards
      Daniel

        @dakapo If you spoofcthe MAC address of the ISP router does that help?

        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 The MAC is already spoofed. So on the pfSense I spoof the MAC of the ISPs Router. Otherwise it doesn't even let me connect.

            Have you looked at top to see if the CPU workload is the bottleneck on upload?

            top -HaSP

              @RobbieTT I checked the 4 CPU-Cores with htop during my last tests and all cores were sleeping.

              The current situation is as follows: I did a factory-reset of the Zyxel yesterday in the afternoon. Since then the upload-speeds are fine. I continue observing the situation and will report about any changes again here.

                That is encouraging news. ๐Ÿ‘
