If a user wants to expose his device to other users within the network, he can do it by the DMZ (Demilitarized Zone) feature of the Linksys router. It is not normally used because it enhances the risks to the other devices that they can easily access. The device in which DMZ is enabled cannot be protected by Internet filters, web filters, or any firewalls, it is open to all the users within the network. You can enable and configure DMZ on your own with the help of the myrouter.local interface.
