The Private network is the wired interface provided by the bridge. This interface includes
a DHCP server and supports dynamic and static IP address assignment. This means any
Ethernet client supporting DHCP can be connected to the wired interface without any
configuration changes. The private network host can communicate with the Airborne
Adapter using the bridges Ethernet IP address on the private network.

Adapter using the bridges Ethernet IP address on the private network.
The Airborne Ethernet Adapter supports NAT Level 3 and as such provides the following
advantages over the more traditional bridge functionality:

A single network IP address on the public network. This simplifies management
of the devices on the network.

A single point of authentication. The Airborne device handles authentication for
the public network, this means a single point of contact for all security interaction,
simplifying deployment for the network.

Port forwarding. Allows you to decide if web page, telnet or FTP access should
be forwarded to the private network or handled by the Airborne Bridge.

Plug-n-Play. In most cases all that is required for full functionality is configuration
of the wireless interface for the target network. This can be done before
deployment to minimize deployment time and complexity.

23.1 Public Network Interface
The public network interface is the Airborne Adapter WLAN port. This interface
must be configured to associate and authenticate with the target network.
Configuration of this interface is covered in section 17.0.

Configuration of this interface is covered in section 17.0.
The public address becomes the target address for all accesses to the host
device connected to the private network. In the example shown in Figure 21, any
device on the public network wanting to communicate with the Host device (IP:
192.168.2.100), would use the IP address 123.45.67.89, the Airborne Ethernet
Adapter will forward all traffic to the private address 192.168.2.100.

The network infrastructure will show the MAC and IP address of the Airborne
Adapter WLAN interface as the network presence, as a consequence of this all
traffic will be identified as being from or to this address.
