Hi I stumbled on ipcamtalk while trying to figure out some networking troubles. I have some IP address being changed on my main router. Ill try to be clear as possible.
I have a farm cam system to monitor my animals. Cams are 1/2 mile from my house connected through long range access points they both have two LAN ports. So i connected my router to the access point so i would have internet were the cams are. Having done that my router is now connected to the NVR's POE NIC IP port.

What is happening is when a new or existing device is connected to the router (ip 192.168.1.1) the router doesnt assign the IP but the NVRs NIC port does (IP 172.64.0.xxx).
So for an example when my Iphone connects to the router the Ip address should be 192.168.1.2 but is assigned 172.64.0.2. Ive made sure that the routers DHCP server is on and the NVR's is off. Ive played around with settings in both units and had no luck. I'm thinking i may have to get two more access points just to have internet out there. I dont want to spend the money for two more and doing the setup. I want to know if theres a way that I can use the existing APs. The AP's are DIP-3226-POE. Theres not much settings in the web interfaces for them. Thanks
 
The NVR is a SR-04NI-LS2-4P. It does have a port for internet to connect to the router. Is there a setting in the router itself that I can block the 172.64.0.1 address. I've tryed a couple things.

You effectively have a loop between the NVR and your router with the single AP they are both connected to. I think you need a second AP there instead of connecting the router and NVR to one. One will provide your local LAN connection for the remote AP and the devices attached to it and the second will connect to the AP that connects to the camera LAN. That will keep them separated, I think. As it stands now you're feeding the camera traffic to the router and the NVR with that single AP. The APs for the camera network will need to be configured just for that network and the APs for the local LAN will need to be configured just for that network.

You should really consider a point to point link like the Ubiquity nanobeams that others are using. Are you able to move the NVR to the cameras side ?. This way camera traffic stays local. The wireless link should just carry the 192.168.1.0 traffic.

You could introduce a small switch at the remote end and connect the access point for the local devices and NVR Internet NIC. All internet traffic will go across the wireless link, you can view cameras via the link, however the recording will be local. Only issue is that you wont be able to use the HDMI output.

The problem is coming from the fact that the NVR has DHCP, or a facsimile thereof, running on the network for the cameras with no way to shut off that DHCP. Since that network is also connected to you regular network, LAN, it assigns a new address to whatever advertises for one and it seems to be faster at that task than the NightHawk.
