he solution to this problem is to set up the router, assign a different port number to each
LAN IP since your port forwarding setup will need to be updated if the camera’s LAN IP
address changes.
Note:
Forwarding ports to your camera does not pose any additional
security risk to your LAN.

Devices (PCs, cameras, etc.) o
For most home networks, a NAT type router serves as the gateway. For business LANs,
the gateway may be a PC running gateway software. In order for any device on your
network to get connected to the Internet, it must know the LAN IP address of your
gateway. If your camera is set up to use DHCP, then it will retrieve this information
automatically from your router.

be sure that you have set the correct gateway IP address in order to connect your
camera to the Internet.

from a PC connected to the LAN. To be sure that your cameras are
accessible by the Internet, you should contact someone you know with
Internet access (preferable broadband) and have them enter your WAN IP
address into their browser.

same as browsing on your LAN except that you must enter your WAN IP address (or
camera domain name if you’ve set up a DDNS service) instead of the LAN IP address.

When accessing multiple cameras over the Internet, you must assign
numbers for each camera. The reason for this is simple. Your gateway router needs
some way of knowing which camera to direct an incoming request to. Unless directed
otherwise, your browser will always send web page requests to port 80. Since port 80
can only be forwarded to one LAN IP address, all incoming web page requests on port
80 will go to this address.

camera. For example, you may set up your second camera to use port 81. When you
want to access this camera, you would tell your browser to use port 81, instead of port
80. In your router’s port forwarding setup, you would need to forward port 81 to the LAN
