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.
