Question about network setup

[Jconerty 0]

Hello all, I have a question about setting up a Hikvision NVR on a static IP network managed by an outside IT company. I keep getting an IP conflict error message about the NIC address conflicting with the IP address. Here is the set up I am using:

 

IPV4 Address: 192.168.254.154

IPV4 Subnet Mask: 255.255.255.0

IPV4 Default Gateway: 192.168.254.10

MTU: 1500

 

Then the DNS setup is

 

Preferred DNS Server: 192.168.254.254

Alternate DNS Server: 192.168.254.250

Internal NIC IPV4 Address: 192.168.254.10

 

So this should all be okay but when I click on apply it gives me an error

 

"Attention: Operation failed, IPv4 addresses of device and Internal NIC conflict. Please set again."

 

And then is tries changing my IPv4 address to : 192.154.168.154

 

The way the system is set up is I have two NVRs on the same network, but I'm getting the same error for both. I had the IT company in charge of the network open up ports 80/81/8000/8001/10554/10555 to gain access to the NVRs.

 

Is this because the internal NIC IP is the same scheme as the external network? I have tried entering a different IP address in the NIC IPv4 spot, but still get the same error regardless. Is this something the IT company needs to change or can it be done through the NVR?

 

Has anyone ever run into this problem or have any ideas about how I can get around it?

 

Thanks in advance for the help!
