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 coming
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 ac-
cordingly 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 for-
warding feature as an NAT traversal function with the precondition that your router must support
the UPnP port forwarding feature.
