Hello, i have exactly the same issue as described here

But device is Zyxel VPN50 (V5.37(ABHL.2) firmware) with ZyXEL SFP-1000T 1000Mbit / s SFP network transceiver module. Is it possible to get it work?

    Hi @AndrewT ,

    It could be related to device boot module. Can you take a screenshot of boot module version and sent me via private message.

    How to check boot module:
    Router# psm
    Router(psm)# atsh

    Hi @AndrewT ,

    We've tested the following configuration on our end:

    • VPN50 (boot module 1.13)
    • Connected to ZyXEL SFP-1000T
    • DHCP provided by other firewalls
    • Port 1 successfully obtains an IP address

    With this setup, we were unable to reproduce the issue you reported.

    To help us investigate further:

    Please check your private messages for instructions and share remote access information, so we can examine your specific configuration.

    Please note: The VPN50 has reached its End of Life (EOL) for firmware development. While we can't provide new firmware updates, we'll explore potential configuration recommendations or workaround solutions for your situation.
