ROUTERS AND FIREWALLS
Another solution is to use one of several small routers/firewalls currently available on the market.
These provide the necessary NAT functionality and allow complete independence for your PC, which can be
switched off or rebooted without affecting the image transmission from your NETWORK VIDEO SERVER.
WINGATE SERVER SOFTWARE:
Running on a single Windows 9x/2000/XP computer, this software allows multiple users simultaneous access
to the Internet through a LAN or higher-speed line, such as xDSL or cable modem connection; and
effectively shares a single Internet connection with almost any type of client computer running TCP/IP.
For more advanced users, the WinGate 3.0 Standard and Pro versions also allow the administrator to change
the IP bindings so that external requests may be routed specifically to your NETWORK VIDEO SERVER –
running behind the WinGate software.
A typical Router Setup for NETWORK VIDEO SERVER looks like this:
You have to create a PORT FORWARDING (sometimes referred to as ADDRESS TRANSLATION or
VIRTUAL SERVER) in the Router configuration.
External port 80 -> forward -> camera local IP : port 80 (TCP)
External port 8080 -> forward -> camera local IP : port 8080 (TCP)
("80" and "8080" are the default ports.)
You can setup multiple local Network IP Cameras in your LAN which can all be accessed from the
Internet with just one public IP Address. The key is to assign different ports to the local cameras.
Example:
Camera1:
External port 81 -> forward -> camera local IP : port 81
External port 8081 -> forward -> camera local IP : port 8081
Camera2:
External port 82 -> forward -> camera local IP : port 82
External port 8082 -> forward -> camera local IP : port 8082
You then can access the camera from the Internet using the following URLs:
http://your_ip_address:81
http://your_ip_address:82
