Port Mapping
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.
3. Click Apply to save the settings.
NOTE!
After port mapping is completed, you may access the Web client of your
NVR by entering the following information in the address bar of your
web browser: router's WAN port IP address:external HTTP port. For
example, if 10.2.2.10 is the IP address and 82 is the HTTP port, then you
enter http://10.2.2.10:82.
