NOTE!
Automatic mapping (Auto) is recommended. Ports will conflict if not

configured properly.
For an NVR with multiple NICs, port mapping should be configured

based on the NIC specified as the default route.
3. Click Refresh and check that Active is displayed for these ports
under UPnP Status.
4. Click Apply to save the settings.
Manual Port Mapping
If your router does not support UPnP, then you need to configure
internal and external ports manually.
NOTE!
The principle of port mapping is that the internal and external ports

of the NVR are consistent with that of the router.
Some routers may require the same internal and external ports for

the NVR and the router.
1. Click System > Network > Port Mapping.
2. Select Manual for Mapping Mode, and then set external ports
manually.
