A DTU Router is a hybrid device that combines the data transfer capability of a DTU with the routing functions of an industrial network router. Unlike a standard DTU, which mainly handles serial data transmission, a DTU Router also provides LAN routing, NAT forwarding, VPN tunneling, and multi-device networking, enabling complex IoT and industrial applications.
