When setting the external port of the router mapping
port, try to use the port between 1024 and 65535.
Avoid using the well-known port 1~255 and the system
port 256~1023 to avoid conflict.
 When deploying multiple devices in the same LAN,
plan the port mapping to avoid mapping multiple
devices to the same external port.
 When performing port mapping, ensure that the
mapped port is not occupied or restricted.
 TCP internal and external ports must be consistent and
cannot be modified.
 Address Filter
The black and white list restricts the PC to log in to the NVR web client by
filtering the IP address or MAC address. There are two types: black list and
white list.
 Blacklist:
1. NVR cannot connect to IPC's IP address or MAC address in the
blacklist.
2. The computer with the IP or MAC address in the blacklist will not
be able to log in to the NVR web page.
