@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.

@PeterGraz here is a guide you can use. https://www.tp-link.com/us/support/faq/3148/

@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

@Sunny1974 replace local network 192.168.0.1/24 with 192.168.0.100/32

@ProSumerTester I have done it like this, a rule for Gateway management Page to block router services (VPN) and then IP Group_Any to block port nat and thing like that.

@ProSumerTester you don't have it on Omada yet. I think it will come eventually :-) what you see is probably region blocking on unifi, you can do that with Omada too but you don't get any fancy...
