Configuring the Primary Bridge Interface
The primary bridge interface is your existing Internet gateway
device. The only step involved in setting up your primary bridge
interface is to ensure that the WAN interface is configured for a
static IP address. You will need this static IP address when
configuring the secondary bridge.
Note:
The primary bridge interface must have a static IP
assignment.
