Your ISP (Internet Service Provider) ’s computer that yours directly connects to. You
may do this via dialup or via a permentent Internet connection. If you have a
firewall, the firewall acts as the gateway to the machines on your
LAN (Local Area Network). The gateway is the IP (Internet Protocol)

send their packets to when they want to talk to the outside world. The cable modem
itself does not have an IP, thus is not considered to be the gateway.
