Hi,
So really need some help please. The system is a Dahua NVR with 3 cameras installed, and for the last 4 years on sky broadband and it all worked properly. The NVR is hardwired via ethernet directly to the router.
Since changing to EE home broadband, their is no remote access available to the DMSS app on mobile devices and the NVR says it is "offline".
I can only view the cameras on the connected TV ( hdmi cable)
EE said they havent any" blocks" in place, however the NVR has pulled through the correct gateway and IP addresses and DHCP is enabled.
The manufacturer, have said there is nothing else they can do and it's a problem with the Broadband provider.
Does anyone have any suggestions/ solution please.
Thanks
 
I'm sorry to say, you probably have a difficult learning curve ahead of you. I'm guessing whatever remote access method you were using before requires IPv4 port forwarding. If you don't know anything about that, then it most likely was done automatically via a router feature called "UPnP" which is likely not enabled on your new router, and turning that on could be the simplest way to get you connected again ... and also get your NVR hacked. Port forwarding is very unsafe and you should not forward ports to your NVR: How to Secure Your Network (Don't Get Hacked!)

If you were connecting directly to your old public IP address or using a dynamic DNS hostname, it is possible that you haven't updated that to match your new public IPv4 address. You didn't share any network configuration details so we really can't say much for sure.

It is also possible that your new internet provider did not give you a dedicated IPv4 address, meaning you are unable to accept any inbound connections using IPv4. If your public IPv4 address (which you should NOT share publicly here) is between 100.64.0.0 and 100.127.255.255 then this is a range commonly used for CGNAT (carrier-grade NAT) which is a fancy way of saying your ISP certainly did not give you your own IPv4 address (this isn't the only range which ISPs use for CGNAT though, just one of the most common).

If you can't accept incoming connections on IPv4 then it is likely you can do it with IPv6, however that is where the worst part of the learning curve comes in because most routers have terrible support for IPv6, most remote access guides ignore its existence entirely, and most people you ask for help won't know what you are talking about.
