Overview of the Cascading Modes
You must apply a cascading mode to the cascading chain. See
Setting
the Cascading Mode
(on page 304).
There are two cascading modes: Bridging and Port Forwarding.
In the following illustration, it is assumed that users enable the DHCP
networking for the cascading chain comprising four devices. In the
diagrams, "M" is the master device and "S" is a slave device.
Illustration:

"Bridging" mode:
In this mode, the DHCP server communicates with every cascaded
device respectively and assigns four
different IP addresses. Each
device has its own IP address.
The way to remotely access each cascaded device is completely the
same as accessing a standalone device in the network.

"Port Forwarding" mode:
In this mode, the DHCP server communicates with the master device
alone and assigns one IP address to the master device. All slave
devices share the same IP address as the master device.
You must specify a 5XXXX port number (where X is a number) when
remotely accessing any slave device with the shared IP address. See
Port Number Syntax (on page 308).
