Hoping to explore this by doing some wireshark with the cameras that are on the 192.168.1.x and seeing if I can determine how they interact with the NVR. In that case my routing tables currently do not allow a connection to be established in this direction. * Perhaps when the NVR first establishes the connection to the camera, it instructs it to make a new connection back to the NVR and they resume their communication over that socket. Still need to figure out why it can't communicate with the camera. So I'll change the NVR back to DHCP and that will set its subnet back to 255.255.255.0.
ADD DEVICE TO REOLINK CLIENT WINDOWS
If I change the subnet mask on the Windows machine to 255.255.0.0 then I can no longer connect to the camera on 192.168.2.x. After your post, I read up on ARP and refreshed my memory on some Layer2 basics, and you're absolutely right. I know just enough networking to be dangerous But I've been thinking about this problem solely from the Layer3 level. Thanks a bunch for your reply, that's very helpful. I agree that it seems reasonable that people might want to connect their NVR to cameras on a different LAN. Or, have I just displayed horrible ignorance? Have you tried setting your Windows machine mask to 255.255.0.0, and you can still communicate with the camera on the other sub-net?
ADD DEVICE TO REOLINK CLIENT MAC
Once I get the MAC address, I'll address my packets to it." But, nobody answers the ARP request, because ARP requests don't go across routers. So, your Windows machine says, "I want 192.168.2.x, and sends that packet to 192.168.1.1, which knows where to find 192.168.2.x" If your Windows machine had a sub-net mask of 255.255.0.0, it would say, "192.168.2.x is on my sub-net, so I'll do an ARP request to find its MAC address. When the IP is not on the same sub-net, it sends those packets to the MAC address of the gateway device, which then knows which router port knows where to find that IP. Then, it sends packets directly to that MAC address. My naive understanding is that when a device wants to send packets to an IP address that is on the same sub-net, it does an ARP request to get the MAC address of the device. (I enjoy the minutia of networking, but have not reached any significant degree of expertise.)
ADD DEVICE TO REOLINK CLIENT SOFTWARE
Clearly it is not necessary for the Windows client software to communicate with the camera.Ĭould you be more specific about how you "configured the routers" to allow traffic from one sub-net to the other? but I haven't been able to find any information that indicates whether this type of outbound connection from the camera to the NVR is necessary. If I know what ports it needs I can fix the router settings. For example, perhaps the camera needs to establish an outbound connection to the NVR? If so, then that would explain my issue because there may be some firewall rule in my router that is blocking this. However, when I try to add this camera through the NVR console (by IP address, exactly how I added the other two cameras) it just shows up as OFFLINE.īecause I am able to access the camera from a laptop on the same subnet as the NVR without any issues, my guess is that there is some difference between how the Windows client software communicates with the camera vs how the NVR and camera communicate. Using a laptop that is on the 192.168.1.0/24 subnet I am able to connect to the 192.168.2.200 camera via both browser and the ReoLink Windows client app.
ADD DEVICE TO REOLINK CLIENT ANDROID
Using a phone that is on the 192.168.1.0/24 subnet I am able to connect to the 192.168.2.200 camera via both browser and the ReoLink android app. I have configured the routers to allow traffic from the first subnet to the camera, and this appears to be working fine. The third camera is in another building with a different subnet for security purposes. The NVR and two of the cameras are on subnet 192.168.1.0/24, and they are playing nicely together. My site has two buildings that each have their own subnets. I have a decent amount of experience with networking and router configuration, and I want to disable UID on the cameras for security purposes. I'm trying to set up a slightly advanced networking configuration for my Reolink cameras and NVR.
