What Is Internet Gateway? - An Internet Gateway is an special computer on the Internet that is connected to two physical networks and relays data messages from one network to the other.

When you open a Website on the Internet, your Web browser actually sends a request message that travels over many physical networks through their gateways in order to reach the Website hosting computer. You can use the "tracert" on a Windows computer to see how many gateways between your computer and a remote computer as shown below (Source: study-ccna.com):
