Configuring the network router for communication across networks

To communicate with the WebDAQ over the internet from a computer connected to a different network, you
must change the network configuration of the network router.
Caution! This procedure should only be performed by a network administrator or computer professional.
Incorrect settings can significantly disrupt a network.
In the following procedure, the WebDAQ is installed on the host LAN, the computer is installed on the client
LAN, and it is assumed that you have successfully connected the device to a local network.
1. Determine the IP address of the WebDAQ – open the Device window from the web interface, and note the
IP Address value on the
2. Configure your router so that the address determined above is a static address. The procedure for
accomplishing this varies between routers; refer to your router documentation for instructions.
3. Configure the firewall/router to forward an unused port to port 80 on the WebDAQ at the IP address
configured for the device.
Note the static IP address assigned to the router – this is referred to as the WAN address.
4. To access your WebDAQ from a remote location, enter the WAN address followed by the port selected
above preceded by a colon in the web browser.
The format of the address entered in the browser is: 000.000.000.000:00000 (WAN address of router:port
selected for the WebDAQ).
