Chapter 2: Networking
26
RG (Residential Gateway) Mode provides basic home networking plus NAT (Network Address
Translation). In this mode, three IP stacks are active:
•
IP Stack 1 - for use by the cable company to communicate with the Cable Modem section only.
This stack receives its IP address from the cable company during CM initialization. It uses the
MAC address printed on the label attached to the Wireless Cable Gateway.
•
IP Stack 3 - for use by you to remotely (i.e. from somewhere on the WAN side, such as at your
remote workplace) communicate with the Cable Modem and Networking sections, to
remotely access the internal web page diagnostics and configuration. This stack is also used
by your cable company to deliver packets between the Internet and the gateway’s networking
section so they can be routed to/from your PCs. This stack requires an IP address assigned by
the cable company from their pool of available addresses. Your cable company may have you
or your installer manually enter assigned addresses into your gateway, or use a DHCP Server
to communicate them, or use a method that involves you entering host names. This stack
uses a MAC address of MAC label + 2 (the MAC label is found on the bottom of the unit). E.g.,
if the MAC address is 00:90:64:12:B1:91, this MAC address would be 00:90:64:12:B1:93.
•
IP Stack 5 - for use by you to locally (i.e. from somewhere on the LAN side in your home)
communicate with the Cable Modem and Networking sections, to access the internal web
page diagnostics and configuration. This stack is also used by the gateway’s networking
section to route packets between the gateway’s Networking section and your PCs. This stack
uses a fixed IP address: 192.168.0.1. It uses a MAC address of MAC label + 4 (the MAC label
is found on the bottom of the unit). E.g., if the MAC address is 00:90:64:12:B1:91, this MAC
address would be 00:90:64:12:B1:95.
With RG Mode, your cable company must provide one IP address for the CM section, plus one for
the Networking section, from their pool of available addresses. With RG Mode, each PC you
connect gets an IP address from a DHCP Server that is part of the Networking section of the
gateway.
