NVR 3216 acting as a DHCP server

[west467 0]

I have a 3216 Dahua NVR that is configured with a static IP address and it is acting as a DHCP server on my LAN. It's handing out IP's in the 192.168.0.X subnet, and my LAN is configured in the 192.168.1.X subnet. Any ideas, as to turning off DHCP server? DHCP is not checked in the network settings.

Hi! I've got the exact same problem- nvr 3216 with static ip handing out 192.168.0.xx ips on my LAN. I've tried everything I can think of, but the problem persists. Did you ever find a solution?

 

One interesting thing is that I have an identical unit with the POE option (4 POE ports, but I don't use those), but it functions perfectly. I'd expect it to be the one more likely to exhibit this type of router behavior.

homeoftheben,

 

I did not find a solution. I have found a workaround.

The 3216 must use the same software as the units with the built in

POE switch, there is no place in the software to turn off the DHCP, other than in

the network settings, one would think that if DHCP was selected here, it would work as a DHCP client getting a address automatically for the NVR. With this option selected, or deselected, I found it kept handing out addresses in the 192.168.0.0 network. The company I bought from, could not assist. I am reluctant to flash the software (NVR) unless someone can verify a new version specifically fixes this problem.

Dahua does not support their product well, this is where you get what you pay for.

 

My work around:

Segment the NVR/CAMERA Network on my home LAN. I did this with two Linksys WRT54G routers running DD-WRT, connecting my CCTV lan segment to the LAN connection on one router, and then connecting the WAN connection to my non-CCTV lan. I turned off the wireless/dhcp on the CCTV router and put some static routes in and configured the port forwarding on both routers. Remote access with iDMSS works fine. Doing this keeps the hosts which request a DHCP address on my non-CCTV lan.

All cameras and my NVR on my CCTV LAN are static IP's. So the NVR gets no requests to hand out IP's.

I see someone asked this recently on the Dahua support site and I believe they were suggesting that you upgrade the firmware. Their support can be found at http://www.dahuasecurity.com/onlinesupport.html Your reseller/distributor should be able to get you the latest firmware.

Thanks for the link, yes I see the recommendations to upgrade the firmware, my retail source, has not offered an upgraded firmware. I have tried to correspond to them thru e-mail, however; after several e-mail attempts they can't seem to help. It's too bad Dahua does not support it's product better in the USA. Still not sure if I want to flash the firmware, the responses in the thread you linked are not very clear. I do not want to brick by NVR with some internet downloaded firmware that may be corrupt, and not directly from the mfg. "please wait new firmware to improve this problem" what version? where to download?
