    Hi @shift

    Welcome to Zyxel community :) 

    Does your DHCP server is located in other subnet of USG40? Or other else?

    Can you provide the topology of your DHCP environment? (IP subnets/ DHCP server/ DHCP clients…etc)

    Hi @shifu,

    I'm trying to have a Captive portal configured on my USG40W, but I can't put it working,

    Can you send me your configuration file? Or maybe can you give some guidelines?


    Thank you so much

    Best regards

    Hi @dpipro

    Just Enable “Enable Web Authentication” at “CONFIGURATION > Web Authentication > General tab”, and add Web Authentication policy for Lan users.

    Incoming interface  : Select the interface on which packets for this policy are received.

    Source Address   : Select a source address or address group.

    Authentication Type : Default-web-portal: the default login page built into the Zyxel Device.

    default-user-agreement: The default user agreement page built into the Zyxel Device
