The LAN prefix and node ID can be obtained by inspecting the IP addresses available on the
“Status” page. The addresses of interest are the IP addresses for each of the active VAPs.
When using the implicit addressing scheme, all of these addresses will fall within a single class
C address space, whereas when using the explicit addressing scheme they can be of arbitrary
size.

Network Address Translation (NAT)
Network Address Translation (NAT) shields the client access interfaces and client devices
connected to the VAPs from the LAN network that the EL-500 is connected to. The EL-500 and
its client devices are able to communicate with devices connected to the external network.
However, devices on the external network cannot initiate communication with any devices
connected to the EL-500.
The advantages of using NAT are:
•
You can easily attach an EL-500 to an existing network. You do not need to modify any
settings on the router on your existing network to forward packets to the IP addresses used
for the VAP interfaces and their client devices.
•
The devices connected to the EL-500 are shielded from the network that the EL-500 is
attached to.
•
You only consume a single IP address on your existing network when connecting the EL-
500 to it.
The main disadvantage of using NAT is
•
You are not able to initiate connections to the client devices connected to the EL-500 from
devices connected to the LAN or points beyond that..
