The WBG-4500-C appliance model has two onboard network interfaces in the middle of its back panel.
Two more network interfaces are made available on a network interface card, which is installed in the card slot on the right.
The network interfaces provide ports, which the operating system assigns names to as follows:
|Position||Interface||Name assigned to port on interface|
|1||Network interface 1||eth0|
|2||Network interface 2||eth1|
|3||Network interface 3||eth2|
|4||Network interface 4||eth3|
