forwarding rule and that rule contains information related to port 2000. That means the internal IP

address (gateway) on your LAN will communicate only with the network device on the LAN configured

to receive the data for port 2000. If you have one network device working with port 2000, only this

device will be able to use port 2000. That means only a port number can be used for a program or

network device. For example if you have a customer using 2 video servers connected on the same LAN ,

you have to give each one a different port to communicate on the same network or over the internet.

2. THE DMZ feature

. ( demilitarized zone )

This feature allows you to open all the ports at once in your router for your Network device

address. The DMZ takes the IP address of the device on your network and forwards all ports. This is

really a nice feature if you are having problems forwarding ports for some program or device. It can be a

life saver if your router will not allow you to properly forward ports. The Network Device

with the DMZ

enabled is now wide open to internet traffic. If the network device attached to the router is a Digital video

recorder or a Video server for example , the unit will not be able to catch a virus, or risk being hacked

because these units are stand alone and designed with an embedded operating systems. On the other

hand there is a risk if you are using a computer instead. If you are using a computer on your LAN it is

better to forward the ports only and not use the DMZ option.

If the user has installed the network

viewer application to view the

camera .The application will try to

access the IP address from router

#2. ( 24.116.50.6 )

The network viewer application must

have the IP from router #2 address

( 24.116.50.6) and the port 2000 to

view the camera..

ROUTER #2

ROUTER #1

The router #2 is been configured to do port

forwarding for the port 2000 for the internal IP

address 192.168.1.125 on the LAN . The router

# 2 has the port 2000 open. When the user from

router #1 access the video server, the data will

go directly to the local IP 192.168.1.125 using

port 2000
