Cablehome (Ch) Mode - THOMSON DCW775 User Manual

Chapter 3: Networking
 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.
