GatewayA machine on a network that serves as an entrance to another network. Also used as shorthand to describe the IP address of that gateway machine. On a DW4000 connection, the gateway for the host is the router at the NOC, while the gateway for Clients is the host itself.
On DW4020 and DW6000 Dynamic connections, the gateway is the modem itself. On DW4020 and DW6000 connections with a static IP the gateway is again at the NOC, although that gateway may be used by a broadband router, which again becomes the gateway for the clients.
Since data passing over the Internet may enter and leave many individual networks, such data will pass through many different gateways. The only one of significance in configuring a computer's Internet connection is the gateway immediately upstream from that computer.
