Chapter 3: Networking

Example: The Wireless Cable Gateway offers a number of built-in web pages which you

can use to configure its networking side; when you communicate with the networking

side, your communication is following this path.

Each packet on the Internet addressed to a PC in your home travels from the Internet down-

stream on the cable company’s system to the WAN side of your Wireless Cable Gateway. There

it enters the Cable Modem section, which inspects the packet, and, based on the results,

proceeds to either forward or block the packet from proceeding on to the Networking section.

Similarly, the Networking section then decides whether to forward or block the packet from

proceeding on to your PC. Communication from your home device to an Internet device works

similarly, but in reverse, with the packet traveling upstream on the cable system.
