Dahua NVR5216 / Netgear R6250 router / Charter ISP

[TechBill]

Anyone having issue remotely accessing NVR6216 that is connected behind a Netgear R6250 router using Charter ISP?

A couple of week ago, i encourages my friend not to buy a boxed system from big box store instead to order Dahua setup with NV^5216 and starlight cameras.

He installed it in his home then he gave me remote access to his computer to complete setting it up on his home network (we live about 4 hours drive from each other). I was able to change the ip address and he set up new password etc on his end. Dahua system is working fine.

I spent hours last night trying to get remote access to the NVR but it just not happening no matter what setting I set on the Netgear R6250 router. I even set DMZ on Netgear temporary to the NVR ip to see even if I can access the web service and still no response from NVR.

The Netgear log show that my ip is connecting to the router and trying to access the NVR ip address and that all the log is showing me so it can't be the Charter ISP or the modem.

Anyone managed to get NVR working remotely using Netgear R6250 router? I am probably overlooking something on my end.

Thank you,
Bill

There was something in the Netgear firmware. After we did a hard factory reset, it started working.

In the wake of all the hacked cameras out there some ISPs may be blocking some of the default ports used by cameras. Setting up a VPN server is the most secure way to do remote access and should provide the same access you'd get if you were at their house.

While VPN server is the most secured way to do it but I discourage anyone who does not have networking knowledge to set it up if their camera system is an all outdoor cameras only unless they are willing to learn networking and pretty much all of them are not willing. They just want to be able to scan and play and I don't want to be their geek in their back pocket either.

All of the folks I helped installed Dahua system are all using cameras outdoor only so I setup their system with upnp and DMSS using Easy4IP (enabled on NVR only) where they can scan the barcode from NVR and start using the app off the bat. No configuring routers or DDNS etc needed.

All of them are pleased with their system and they never really had any issue with this setup. But they are aware that this setup method does have a higher chance of being hacked. Since it all outdoor cameras setup once the hacker gain access then only thing that useful to them is to use the storage space on NVR to store all their porns or pirate movies etc. They can view all the outdoor cameras but the hackers won't see anything worthwhile over what the next door neighbors can see from there.

You didn't specify you were using easy4ip earlier...

You are very wrong...once a hacker has access to the nvr or cameras they now how control of a pc on your network anything is fair game. The units are now also capable to be used for botnets as we have seen before with dahua....you have now also enabled upnp on their router which will allow any upnp device to poke holes in the firewall no questions asked...this is why we see all the problems we do today..
