Hi, I need some advice. I have a Teltonika RUT955 device. I have created a wifi and I need to make it so that whoever connects to this wifi cannot access the internet. I am using a data sim card here. I also use OpenVPN. I simply need that OpenVPN will have access to the internet, but whoever connects to the wifi will not have access to the internet, they will only have access to all the devices that are connected to the Teltonika lan. Thanks a lot
