Cascading Multiple EMX Devices for Sharing Ethernet Connectivity
You can have multiple EMX devices share one Ethernet connection by
cascading them via USB.
Warning: To upgrade an existing USB-cascading chain from a
version older than 3.3.10, you must start from the last slave device
and so on until the master device. Otherwise, a networking issue
occurs. See
Upgrade Guidelines for Existing USB-Cascading Chains (on
page 270).
The first one in the cascading chain is the master device and all the other
are slave devices. Only the master device is physically connected to the
LAN -- wired or wireless.
Each device in the chain is accessible over the network, with the bridging
or port-forwarding cascading mode activated on the master device. See
Setting the Cascading Mode
(on page 162).

Bridging: Each device in the cascading chain is accessed with a
different IP address.

Port Forwarding: Each device in the cascading chain is accessed with
the same IP address but with a different port number assigned.
Cascading restrictions:

In the bridging mode, the master device can have "only one"
connection to the network.
Note: The port forwarding mode does NOT have such a restriction. In
the port forwarding mode, you can enable both wired and wireless
networking.
