– DMZ
IP Address: IP address of the DMZ host.
Port Begin/Port End: Beginning port number and end port number. Packets
destined for the LAN interface of your KT101 with destination port numbers within
this range are forwarded to the corresponding ports of the DMZ host.
For example, the settings in Figure 3-10 specify to forward packets with destination
port numbers ranging from 20 to 1023 to the corresponding ports of the DMZ host,
whose IP address is 192.168.254.2.
Note:
For a port that is within the range specified by the Port Begin and Port End parameters and
is used by a local service of your KT101, the received packets are not forwarded to the
DMZ host. Your KT101 usually uses port 23, 67, 80, 123, and 161. In addition, the VoIP
protocol stack uses some other ports. Consult your carrier or administrator for details.
Caution:
Make sure the DMZ host uses a static IP address that is in the same network segment as
that of the PC interface on your KT101.
Enabling DMZ function increases possibility of being infected by viruses.
2) Configuring static port mapping
You can map a port of the LAN interface to a port of the host connected to the PC
interface, so that all packets destined for the specified port of the LAN interface are
forwarded to the specified port of the host that is connected to the PC interface.
(The host herein is referred to as an internal host.) Up to four pairs of ports can be
mapped on your KT101 by selecting Enable from the drop-down lists on the Static
Port Map section shown in Figure 3-9. Figure 3-11 is the page displayed when you
select Enable from the [Item1 Enable] drop-down list.
