Note: In Figure 14 all the IP addresses are taken as an example. The WAN IP addresses are normally 
provided by your ISP. Whereas, the LAN IP addresses can be set manually to any range which is 
within the subnet of the Modem/Router/switch. 
 
Use a cross-over LAN cable to connect the instrument directly to a computer, or a standard LAN 
cable for connection to a Modem/Router/Switch as shown in Figure 14. The computer could be 
connected to the Modem/Router using either CAT5 cable or a wireless connection, but the 
instrument must be connected using CAT5/6 cable.

4.3.2  Port Forwarding on Remote Modem/Router Setup  
When using the network port to connect to the router / modem with NAT enabled, you will need to 
add IP mapping to ensure that data is forwarded through to the desired port. This is known as port 
forwarding. To set-up the port for the instrument, you will need to go into the modem/router 
configuration. Normally, you will see the port forwarding setup under Port Forwarding, NAT or Port 
Mapping menu. Below is an example port forwarding setup.
