Device, it doesn’t know how many PCs existed inside privacy LAN. This IP Sharing
Device is also acted as a firewall.
Thus, we have changed the setting of IP Sharing Device; let public PC has the
opportunity to access LAN devices, e.g. IP Camera.
We can achieve this goal by enable Reversal NAT (RNAT) function of IP Sharing Device.
1. “Virtual Server”: Many routers have “Virtual Server” support. You must forward the
WAN 80 TCP port to LAN IP Camera’s IP and Port. (If you visit 210.82.13.21’s 80
port outside, you will be forward to LAN 192.168.0.2’s 80 port).
2. Another method is the “DMZ Host”. If enabled to use a LAN device as the DMZ host,
the outside PC will be able visit this LAN device directly, as if there is no IP Sharing
Device exists. This method support only one LAN device exposed to the WAN. Thus,
if you have more IP Cameras, you have to use the above method.
Take D-Link
(http://www.dlink.com) DI-604/DI-614+/DI-624 as an example:
1) Login to your router;
2) In WAN configuration, input the PPPoE username and password provided by
your ISP;
3) Click Advanced on Top of homepage;
4) Click Virtual Server (Note: If you use Virtual Server mode, you must turn DMZ
host function off first. DMZ Host function will disable all Virtual Server function)
5) Input the following information on page:
Enabled/Disabled: Enabled
Name: C1060
Private IP: Input IP Camera’s Address, e.g. 192.168.0.151
Protocol Type: TCP
Private Port: 80
Public Port: 80
Schedule: Always
6) Click Apply to save. IP Camera can be accessed in WAN.
