Troubleshooting bandwidth issues with AT&T BW210 fiber and Gold SE

I am having issues getting good speeds when connected directly to the Firewalla Gold SE that I just installed.

I am an AT&T fiber customer with 1G service through a BGW210-700. Speed test directly to the gateway looks good:

I have my FW setup in router mode and connected to the gateway and it has the my public IP address, but I am only getting about half my download bandwidth and my upload is extremely slow. I have troubleshooted from the iOS app, but ended up running the speedtest cli directly on the FW to rule out anything:

pi@Firewalla:~/tools (Firewalla) $ ./speedtest

   Speedtest by Ookla

      Server: AT&T - New Orleans, LA (id: 47748)
         ISP: AT&T Internet
Idle Latency:    36.97 ms   (jitter: 1.61ms, low: 35.81ms, high: 38.50ms)
    Download:   567.81 Mbps (data used: 819.3 MB)
                 44.85 ms   (jitter: 23.02ms, low: 34.15ms, high: 400.84ms)

                 35.05 ms   (jitter: 4.26ms, low: 34.06ms, high: 97.19ms)
 Packet Loss:     0.0%

Could there possibly be some setting on the FW that I am missing that is degrading my bandwidth?

    Thanks. After researching quite a bit I found that the BW210 could have some issues in IP passthrough mode. I am going to try the FW in Simple Mode tomorrow to see if it is indeed isolated to the AT&T passthrough.

    That would be unfortunate because then I would be double NAT.

    I do know there are many people using passthrough mode with the ATT modem, if you have any specific issues, please post, I am sure others can help you out.

    I am getting better speeds without IP passthrough, but still not what I would expect.

    After chatting with AT&T support it was the AT&T ActiveArmor product that was causing the slowdown. The agent deactivated the product and I am now getting speeds as expected. For others that come across this, you can deactivate the product yourself in AT&T Smart Home Manager mobile app.

    So I spoke to soon. I was still experiencing slow downs, while not quite as severe, I am still not getting gigabit speeds from my AT&T fiber modem to my router. I have Smart Queue turned off. Is there anything else I can check on the FW side?
