A gateway is an entrance point from one network into another network. The device has an IP address that is designated as a gateway address to your network. If you want to send Internet traffic from you network to another network you send it to the gateway and expect it to get to where it is supposed to go. The gateway device only has to provide one gateway address in order to be considered a gateway, but needs to be connected to both networks.
