SBG7400AC2: Bridge Mode Setup

By default, the SBG7400AC2 operates as a gateway, and provides Internet access for multiple devices (up to 253 devices), connecting to the SBG7400AC2.  The SBG7400AC2 serves as a modem and a router and keeps the devices in the Local Area Network (LAN) hidden.  In certain situations, it may be desired to disable the router function of the SBG7400AC2, and have it operate as a modem only.  This can be accomplished by configuring the SBG7400AC2 for Bridge Mode.  When Bridge Mode is enabled, the router function is turned off and the device directly connected to the SBG7400AC2 will receive the Public IP address from the Cable Provider.  This document contains the following sections:
