Vivotek FD9167-H User Manual page 33

For example, your router and IP settings may look like this:
Device
Public IP of router
LAN IP of router
Camera 1
Camera 2
...
Configure the router, virtual server or firewall, so that the router can forward any data com-
ing into a preconfigured 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
122.146.57.120:8000
122.146.57.120:8001
...
When properly configured, 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 configuration page, please open the ports
accordingly on your router. For example, you can open a management session with your
router to configure access through the router to the camera within your local network.
Please consult your network administrator for router configuration if you have troubles with
the configuration.
For more information with network configuration options (such as that of streaming ports),
please refer to Configuration > 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.
