in USG FLEX H Series

Hello, after upgrading 2 USG FLEX 100H devices from version 1.20 to V1.30(ABXF.1) there are multiple problems.
1.- Performance-bandwidth problems (The client has 1G internet access on the WAN and we only have 100M from LAN to WAN
2.- Sessions and traffic are not shown in the logs or Dashboard
3.- Traffic cannot be seen in the logs.
4.- Traffic between WAN and LAN is slow.
This is a big problem for my client and I need to resolve it as soon as possible.
Thank you.

    Hi @Pedroj

    To better understand and investigate the issues you're experiencing, it would be helpful if we could access your firewall remotely via the web GUI.

    You can follow the steps in this guide to enable HTTPS Web GUI access from the WAN:

    How to allow HTTPS Web GUI Access from WAN? (USG FLEX H) — Zyxel Community

    Once enabled, please share the login credentials for your device with us via a private message.

    Hi @Pedroj

    Thank you for sharing the remote web GUI details via private message. We're still investigating your issue.

    In the meantime, we would greatly appreciate it if you could provide us with the following additional information:

    1. How did you test the performance?
    2. What were the performance results before upgrading to version 1.30P1?
    3. Does the 1G internet access on the WAN refer to the ge1_PPP interface?

    Hello,
    We tested the performance by connecting only one PC directly to the Firewall.
    Before the 1.30P1 update, the client had the maximum ISP speed.
    800M symmetrical and even more.
    Yes, the 1G access is PPoE.
    WAN2 is 4G
    Could you send me version 1.20 to try to give him a quick solution if the solution takes a while?
    The client is very upset.

    Hi @Pedroj

    As discussed in our private messages, we’ve identified that both the throughput and session issues were caused by NAT rules. This fix will be included in an upcoming official firmware release, scheduled for early 2025.
