A method for converting a protocol in a gateway and the gateway thereof are provided to connect incompatible networks having different protocols, thereby converting a protocol. A first communications module(110.1) receives a first packet from a first in-network originating device. A memory(120) stores a destination address conversion table. A controller(130) extracts the first destination address from the first packet received by the first communication module. When the first destination address belongs to the second network, the controller converts the first destination address into the second destination address corresponding to a protocol of the second network by referring to the destination address conversion table stored in the memory and generates and transmits the second packet including the second destination address to the second network. The second communications module(110.2) transmits the second packet generated by the controller to the second network. The third and N communication modules(110.3,110.N) are modules according to a communication method except the first and second communication modules. When the first destination address belongs to another network not the second network, the controller transmits the second packet to a corresponding network through the third or N communication modules. |
