NIC and Gateway Conflict Network Crash

NIC and Gateway Conflict Network Crash

Unfortunately, if the NVR gets a DHCP assignment of 192.168.1.1 as the gateway address, then that conflicts with the IP address held by the internal NIC, resulting in the NVR assigning 0.0.0.0 as the gateway. We tested this on our own network using an Internal NIC address of 192.168.99.254. This is clearly unintended. There also appears to be some evidence that even if the gateway is not *.1, using the same subnet results in network IP conflicts. This can completely remove the NVR from the network in some observed instances.

We suggest changing the Internal NIC (IPv4) address to a class B private subnet, such as 172.16.1.1. Initial testing shows that the cameras are unaffected by such a change. Class B subnets are also exceedingly rare on most router configurations, which should then remove the issue of network conflicts almost entirely.
