AirPort Network Designs
How It Works
•
The base station uses your Ethernet network to communicate with the Internet and
receives power through the Ethernet WAN ( ) port.

AirPort clients access the Internet and the Ethernet network through the AirPort
Extreme Base Station.
Extreme Base Station.
Note: AirPort Extreme Base Stations that support Power over Ethernet (PoE), are set up
by default to act as a bridge, and the “Share a single IP address (using DHCP & NAT)”
option is not selected. Use the Network pane of AirPort Admin Utility if you want to
select the “Share a single IP address (using DHCP & NAT)” option.

What You Need for a Power Over Ethernet Connection
What to Do
Follow the instructions in the section, “You’re Using an Existing Ethernet Network” on
page 37, to set up the AirPort network.

You can turn off the base station’s Internet sharing features (which provide IP addresses
to AirPort computers using DHCP or NAT) to allow bridging between the network’s
wireless and wired computers. With bridging turned on, AirPort computers have access
to all services on the Ethernet network, and the base station does not provide Internet
sharing services.

Using the base station as a bridge can be a way to address incompatibilities between
the base station’s Internet sharing features and your ISP’s connection method.

To use the base station as a bridge, all AirPort and Ethernet computers need to have
IP addresses set manually and use the same subnet mask.
