Gateway refers to a piece of networking hardware as a network node equipped for interfacing with another network that uses different protocols. A network gateway can be implemented completely in software, completely in hardware, or as a combination of both. o. In the network for an enterprise, a computer server acting as a gateway node is often also acting as a proxy server and a firewall server.
