Trying to see IP camera from internet outside LAN

frananpi asked 2 years ago

I have an AT&T wireless internet service. AT&T issued a wireless modem device (which is a cellular phone 4G type of wireless connection) to be connected to the USB port of the device you want to connect to the internet. In my case I connected the AT&T modem to a Cradlepoint CTR500 router which enables additional devices to be connected to the internet wirelessly of via Ethernet cable. In my case I connected the Cradlepoint CTR500 to a D-Link DIR-815 router via the Ethernet cable. Now I am able to connect all my internet capable devices from anywhere in my house. I added a wireless IP camera to my LAN, configured with a static IP address works perfectly. The problem is enabling to see the camera images from outside my wireless LAN environment. None of the IP addresses stated by the routers are recognized or reachable through the internet from any network outside mine. Can you explain what is the problem? Is it a technical limitation of the AT&T wireless internet service? Whatismyip.com shows 166.205.xx.xx but ipconfig shows 192.168.xx.xxx.

Thanks for your question frananpi.

The IP you see at our home page is your external IP. The IP you see at the command prompt after typing ipconfig is your internal IP.

To view your camera from outside your LAN, you will need to forward the port the camera is listening on through the Router it is connected to. If the Internet connection goes through both routers, you will need to forward the same port from the first router to the second router and then to the camera.

I think you will find that the IP address you get on the 4G device is going to change frequently which means you will probably need to use some type of Dynamic DNS service to maintain the external connection.
