: How DDNS can link to 3G simcard dynamic IP I have CCTV that work via 3G (use simcard). I can access it directly using dynamic IP but as it keep changes, I won't be able to access it. My

There's never a "DDNS provider knows my IP!" situation. It is the endpoint device holding your actual nated (almost for sure private) IP who connects to DDNS provider instead.

You need to make a port forwarding from the router ( located in 3G ISP ) and this is a challenge !

The CCTV software that uses the 3G will need to support DDNS and from what you say that is the case. You now need a DDNS provider... personally I recommend DynDNS which offer some of the best DNS solutions that are reliable and not to expensive. I recommend the pro package which in their own short description sounds exactly what you need:


Looking to access your computer, DVR, webcam or camera system remotely
without having to remember a confusing (and ever changing) IP address?
Try DynDNS Pro, a great option for those who need Dynamic DNS and
Remote Access capabilities without any bells, whistles or fireworks.


There are many other DDNS providers however and you should take a look here for free DDNS and other paid DDNS services. If the CCTV system is important I recommend a paid service as they have a habit of stop working on free based DDNS
