Configuring Routable and Bridgeable Interfaces
Making Interfaces Routable (IP-Enabled)
A routable or IP-enabled interface is simply one that has been
assigned an IP address. IP-enabled interfaces are capable of
forwarding IP packets. You can assign IP addresses to any LAN or
WAN interface.
f For information about assigning IP information to LAN
interfaces (e.g., eth-0 and usb-0), see Chapter
4.
f For information about assigning IP information to WAN
interfaces, see Chapter
5.
Making Interfaces Bridgeable (Bridge-Enabled)
When you make an interface bridgeable, you enable the software to
receive Ethernet packets through that interface, for forwarding
through the device’s other bridgeable interfaces. If an interface is
not bridgeable, it can only forward IP packets (assuming the
interface has been IP-enabled).
Note
If you create a LAN or WAN interface, it must be IP-enabled,
bridge enabled, or both. An interface that has no IP address and is
not made bridgeable will not pass any data.
Follow these instructions to specify which interfaces can perform
bridging.
1. Log into Web Configuration and click the Bridging tab.
The Bridge Configuration page displays:
Figure 30. Bridge Configuration Page
The Bridge Configuration page provides links (shown in red) to
the System Mode page, where you can enable or disable the
corresponding bridging services. The Bridge Configuration
page also displays a table for specifying the interfaces that
support bridging. The table may be empty if bridging has not yet
been configured.
