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.
The 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 the LAN interface in
the AP case).
Primary/Secondary DNS IP
: The Domain Name System (DNS) is an internet "phone book" which
translates domain names into 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 is used for
management purposes of the device.
The secondary DNS server IP address is
optional
. It is used as the fail-over in case the primary
DNS server becomes 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 contrariwise
direction in "Station or Station WDS" mode.
NAT
is implemented using the masquerade type firewall rules. NAT firewall entries are stored
in the IP tables and NAT tables while the device is operating in router mode. Please refer to the
IP tables tutorial for a detailed description of the NAT functionality in router mode. Static routes
should be specified in order for the packets to pass-through the based device, if the NAT is
disabled while operating in router mode.
Enable DHCP Server:
The
Dynamic Host Configuration Protocol (DHCP) server assigns IP addresses
to clients who will associate with the wireless interface while the device is operating in AP/AP WDS
wireless mode. It also assigns IP addresses to clients that will connect to the LAN interface while the
device is operating in station or station WDS mode.
Range Start/End:
This range determines the IP addresses given out by the DHCP server to the client
devices on the internal network that use dynamic IP configuration.
Lease Time:
The IP addresses given out by the DHCP server will only be valid for the duration
specified by the lease time. Increasing the lease time helps to ensure client operation without
interruption but could cause potential conflicts. Lowering the lease time will help to avoid potential
address conflicts, but it could also cause interruptions to the client while it acquires new IP addresses
from the DHCP server.
