In the Bridging mode, each cascaded device has only one IP address.
In the Port Forwarding mode, each cascaded device can have multiple IP addresses as long as the
master device has multiple network interfaces enabled/configured properly.
For example:
When the master device has two Ethernet ports (ETH1/ETH2), you can enable ETH1, ETH2 and
WIRELESS interfaces so that the Port-Forwarding chain has two wired IP addresses and one
wireless IP address.
Port Number Syntax

any cascaded device, you must assign an appropriate port number to it.
Master device: The port number is either
5NNXX
or the standard TCP/UDP port.
Slave device: The port number is
5NNXX
.
5NNXX port number syntax:
