Configure Port Mapping (NAT)

Two ways are provided for port mapping to realize the remote access via the cross-segment network, UPnP™ and manual mapping.

If you want to enable the UPnP™ function of the device, you must enable the UPnP™ function of the router to which your device is connected. When the network working mode of the device is set as multi-address, the Default Route of the device should be in the same network segment as that of the LAN IP address of the router.

Universal Plug and Play (UPnP™) can permit the device seamlessly discover the presence of other network devices on the network and establish functional network services for data sharing, communications, etc. You can use the UPnP™ function to enable the fast connection of the device to the WAN via a router without port mapping.

  1. Go to System > Network > TCP/IP > NAT.

  2. Check Enable.
  3. Select Mapping Type as Manual or Auto.

    • Auto: If you select Auto, the port mapping items are read-only, and the external ports are set by the router automatically.

    • Manual: If you select Manual, you can edit the external port on your demand by clicking to activate External Port Settings.

    Note:

    • You can use the default port No., or change it according to actual requirements.

    • External Port indicates the port No. for port mapping in the router.

    • The value of the RTSP port No. should be 554 or between 1024 and 65535, while the value of the other ports should be between 1 and 65535 and the value must be different from each other. If multiple devices are configured for the UPnP™ settings under the same router, the value of the port No. for each device should be unique.

  4. Enter the virtual server setting page of router; fill in the blank of Internal Source Port with the internal port value, the blank of External Source Port with the external port value, and other required contents.
    Note:

    • Each item should be corresponding with the device port, including server port, http port, RTSP port and https port.

    • The virtual server setting interface below is for reference only, it may be different due to different router manufactures. Please contact the manufacture of router if you have any problems with setting virtual server.
