@DerTom Try and set satic ip on controller,

@DerTom another thing, what router and switcher do you have? OC300 is a network controller to manage omada routers and switches, access points. it doesn't have any of this built in

@DerTom I don't have an OC300 myself but look in global settings and one of the menus you have available there. system settings or controller settings maybe.

@YuriyB I don't think you can do it stand alone, but if you adopt the router to an Omda controller you get up to 5 networks in custom IP configuration
