The public network interface supports the Airborne discovery protocol and will
respond to discovery requests issued on the public network.
9.2 Private Network Interface
The private network interface is on the Ethernet port of the Airborne Bridge. The
interface supports a single Ethernet client with either a static or DHCP sourced IP
address. This interface needs minimal configuration and requires the parameters
in Table 2 to be configured.
Table 2 - Private Network Interface Configuration
Command Description
eth-ip
This is the IP address the DHCP server will lease to the client when the client is
using DHCP.
eth-subnet
This is the subnet mask the DHCP server will provide to the client when the
client is using DHCP.
eth-gateway
This is the IP address of the Ethernet Interface on the Airborne Ethernet Bridge
and is the target address for communications between the Ethernet client and
the Airborne Bridge.
eth-mode
The Ethernet interface supports the following configurations, this parameters
determines the default mode of the interface.
auto Auto negotiate
10half 10Mbps, half duplex
10full 10Mbps, full duplex
100half 100Mbps, half duplex
100full 100Mbps, full duplex
It is recommended that auto be used as this will provided the greatest level of
compatibility on the Ethernet interface.
The private network supports the Airborne discovery protocol and will respond to
discovery requests.

The subnet for the private network IP addresses (Ethernet Client and Gateway) and
public IP address (802.11), obtained by the module via the wireless interface, MUST
NOT be the same.
Failure to observe this requirement will result in unpredictable behavior of the bridge.
When attempting to make an out-bound connection to a device on the public
network, the public network IP address of the device should be used e.g. In
Figure 6 the client with address 192.168.2.100 wants to connect to an FTP
server, with the address of 123.45.67.99, on the public network to perform a
firmware download. The FTP address that would be used in the ftp-server-
address parameter would be 123.45.67.99. Note that this is not within the
subnet of the Ethernet client, however the NAT router will do the necessary
address translations and packet header manipulations to ensure the out-bound
and in-bound connections are maintained.
