    There is a scenario make you cannot remove the LAN interface, that is, there is at least one port assigned to the LAN interface. Please go to Site-wide > Configure > Firewall > Port, and make sure there is no port assigned to LAN3.
    If there is no port assigned to LAN3 but still unable to delete LAN3, please enable Zyxel Support Access and provide your org/site via private message, I will check on this for you.

    Previously, this interface was removed without problems. So I don't understand why I can't delete it now.

    Which model do you use? Is your LAN3 a newly created or a default interface?
    For on-premises mode devices, only models above 500 can remove the default interface. (USGFLEX500/700, ATP500/700/800)
    For Nebula mode devices, all models can remove the default interface.

    you must remove all the references to your LAN3 first. Select the interface and click References, and you can see all the references to your LAN3. If still cannot do it, please provide your configuration via private message, I will check on this for you

    There is a button References, click on it and it will pop out a window to show all the references.
