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 it's local network while the device is operating in AP/APWDS wireless mode and in
the contrariwise direction in "Station/StationWDS" 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. Please refer to the
iptables
tutorial
for detailed description of the NAT functionality in Router mode.
Static routes should be specified in order the packets should pass-through the based device if the
NAT is disabled in while operating in Router network mode.
Enable DHCP Server:
Dynamic Host Configuration Protocol (DHCP) Server assigns IP
addresses to clients which will associate to the wireless interface while the device is operating in
AP/APWDS wireless mode and assigns IP addresses to clients which will connect to the LAN
interface while the device is operating in Station/StationWDS mode.
Range Start/End:
This range determines the IP addresses given out by the DHCP server to client
devices on the internal network which 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 time ensure client operation without interrupt, but could
introduce potential conflicts. Lowering the lease time will avoid potential address conflicts, but
might cause more slight interruptions to the client while it will acquire new IP addresses fromthe
DHCP server.
DHCP Fallback IP
: In case the external network interface of the Router is placed in Dynamic IP
Address mode (DHCP) and is unable to obtain an IP address from a valid DHCP server, it will fall
back to the static IP address listed here. In case the IP settings of the device are unknown, they can
be retrieved with the help of the UConfig utility and should be started on the administrator PCwhich
resides on the same network segment as the device.
Port Forwarding Settings
Port Forwarding
: Port forwarding allows specific ports of the hosts residing in the internal
network to be forwarded to the external network. This is useful for number of applications
such as FTP servers, gaming, etc. where different host systems need to be seen using a single
common IP address/port. Port Forwarding rules can be set in Port Forwarding window, which
is opened by enabling the Port Forwarding option and activating the Configure button.
Port Forwarding entries can be specified by using the following criteria:
Private IP
is the IP of the host which is connected to the internal network and needs to be
accessible from the external network;
Private Port
is the TCP/UDP port of the application running on the host which is connected to
the internal network. The specified port will be accessible from the external network;
Type
is the L3 protocol (IP) type which needs to be forwarded from the internal network.
Public Port is the TCP/UDP port of the based device which will accept and forward the
connections from the external network to the host connected to the internal network.
Comments
is the informal field for the comment of the particular port forwarding entry.
Few words about the particular port forwarding entry purpose are saved there usually.
Enabled flag enables or disables the effect of the particular port forwarding entry.
