In the output of route -n, there is a column named "gateway".



What can be a gateway?



I thought a gateway between two networks is a device manually designated to be a gateway, out of several devices connected to both networks.



But now I wonder whether a gateway between two networks is just any device




  • with two network interfaces connected to the networks respectively, and


  • with a routing table allowing packets to be transmitted from a network to the other (Is it correct that every device in network(s) has a routing table?)
    ?



Thanks.
