What is a network gateway port?

A network gateway port is a physical or virtual connection point within a network device, such as a router or switch, that serves as an entry or exit point for data traffic between different networks. It acts as a bridge or interface between different network protocols, allowing communication and data transfer between networks with different addressing schemes or protocols. The gateway port is responsible for routing and forwarding data packets to the appropriate destination network based on the destination IP address.
