A gateway is a piece of equipment that performs various networking functions, like filtering IP packets (‘firewalling’), Network Address Translation (‘NAT’), routing of IP packets across one or more networks (‘routing’), and serving up IP addresses to clients attached to the network (‘DHCP’). Quite often gateways are called ‘routers’, although as we’ve just seen, gateways do more than just route network traffic.
