Netmask
This is used to define the device IP classification for the chosen IP address range.
Address 255.255.255.0 is a typical netmask value for Class C networks, which support
IP address range 192.0.0.x to 223.255.255.x. Class C network Netmask uses 24 bits to
identify the network (alternative notation "/24") and 8 bits to identity the host.

Gateway IP
This is the IP address of the host router that resides on the external network and
provides the point of connection to the next hop towards the internet. This can be a DSL
modem, cable modem, or a WISP gateway router. The device will direct all the packets
to the gateway if the destination host is not within the local network.

Gateway IP address should be from the same address space (on the same network
segment) as the device's external network interface (wireless interface in the Station
case and LAN interface in the AP case).

Primary/Secondary DNS IP
The Domain Name System (DNS) is an internet "phone book" that translates domain
names to IP addresses. These fields identify the server IP addresses where the DNS
requests are forwarded by the device.

The primary DNS server IP is mandatory. It is used by the DNS Proxy and for the device
management purpose.

A secondary DNS server IP address is optional. It is used as the fail-over in case the
primary DNS server will become unresponsive.

Enable NAT
Network Address Translation (NAT) enables packets to be sent from the wired network
(LAN) to the wireless interface IP address and then sub-routed to other client devices
residing on its local network while the device is operating in AP/AP WDS wireless mode
and in the opposite direction in "Station/Station WDS" mode.
(LAN) to the wireless interface IP address and then sub-routed to other client devices
residing on its local network while the device is operating in AP/AP WDS wireless mode
and in the opposite direction in "Station/Station WDS" mode.
NAT is implemented using the masquerade type firewall rules. NAT firewall entries are
stored in the iptables NAT table while the device is operating in Router mode. Refer to
available iptables information for details of NAT functionality in Router mode. Static
routes should be specified in order that the packets pass through the device if NAT is
disabled while operating in Router network mode.

Enable DHCP Server
Dynamic Host Configuration Protocol (DHCP) Server assigns IP addresses to clients
that will associate with the wireless interface while the device is operating in AP/AP
WDS wireless mode and assigns IP addresses to clients that will connect to the LAN
interface while the device is operating in Station/Station WDS mode.
