For example, your router and IP settings may look like this:
Device IP Address: internal port IP Address: External Port (Mapped
port on the router)
Public IP of router 122.146.57.120
LAN IP of router 192.168.2.1
Camera 1 192.168.2.10:80 122.146.57.120:8000
Camera 2 192.168.2.11:80 122.146.57.120:8001
... ... ...
Congure the router, virtual server or rewall, so that the router can forward any data com-
ing into a precongured port number to a network camera on the private network, and
allow data from the camera to be transmitted to the outside of the network over the same
path.
From Forward to
122.146.57.120:8000 192.168.2.10:80
122.146.57.120:8001 192.168.2.11:80
... ...
When properly congured, you can access a camera behind the router using the HTTP
request as follows: http://122.146.57.120:8000
If you change the port numbers on the Network conguration page, please open the ports
accordingly on your router. For example, you can open a management session with your
router to congure access through the router to the camera within your local network.
Please consult your network administrator for router conguration if you have troubles with
the conguration.
For more information with network conguration options (such as that of streaming ports),
please refer to Conguration > Network Settings. VIVOTEK also provides the automatic
port forwarding feature as an NAT traversal function with the precondition that your router
must support the UPnP port forwarding feature.
