Overview of System Operating Modes
The Ethernet Modem Router can operate in Bridging mode, Routing
mode, or Routing and Bridging mode. You can view the currently
configured mode in the System View table on the Home page, as
shown in Figure 29.
Figure 29. Viewing the Operating Mode
The system mode that displays is not configured using a single
setting. Rather, it is determined at system startup based on whether
the device’s LAN and WAN interfaces are configured with IP
information (i.e., are “IP-enabled”), and whether the Bridging setting
on the System Mode page is enabled or disabled. The System
Mode page is located in the Home tab and is shown in Figure 31 on
page 80.
f When the Bridging setting on the System Mode page is
disabled, then the system mode will display as “Routing.”
f When the Bridging setting is enabled and at least one LAN
or WAN interface is IP-enabled, then the system mode will
display as “Routing and Bridging.”
f When the Bridging setting is enabled and no interfaces are
IP enabled, then the device is considered to be in Bridging
Mode. Note, however, that in this case you would not be
able to access Web Configuration; without being IP-
enabled, the Ethernet interface could not communicate
using the Internet protocol HTTP which is used to display
information in your Web browser.
Instead of focusing on selecting a system mode of operation, users
should ensure that the appropriate settings are in place to enable
communication with the ISP and to provide the required LAN
services. The correct operating mode will be selected automatically
when these settings are properly configured.
The following sections describe how to configure IP-enabled and
bridge-enabled interfaces and how to enable/disable the Bridging
setting. Several common configurations are described on
pages 81-83.
