This screen lets you configure port forwarding, DMZ, and reserved ports range settings.

Port Forwarding Settings

Enable

. Select

yes

or

no

for each port forwarding entry, which defines a port range to be forwarded to a server.

The default is

no

.

Service Name

. Enter the name of the service or application.

Starting Port

. Enter the starting port number of the forwarded port range.

Ending Port

. Enter the ending port number of the forwarded port range.

.

Server IP Address

. Enter the IP address of the server, 192.168.0.x (x being a different number for each server

you specify).

DMZ Settings

Enable DMZ

. DMZ hosting forwards all ports at the same time to one computer. This allows one local user to be

exposed to the Internet for use of special-purpose services such as videoconferencing. Select

yes

or

no

from the

drop-down menu. The default is

no

.

DMZ Host IP Address

. Enter the IP address of the DMZ host, 192.168.0.x (x being the number for the computer

you want to specify). Use the Static DHCP Lease Settings section on the

LAN Setup

screen, so the DMZ Host

keeps this IP address; otherwise, its IP address may change.

System Reserved Ports Range

Starting Port

. This port range defines the random TCP/UDP ports used by the application running on the System.

They cannot be used by port forwarding or DMZ. Enter the starting port number of the reserved ports range. The

default is

50000

.

Num of Ports Reserved

. Select the number of ports you want to reserve:

256

,
