LI-COR LI7200RS - Port Forwarding

enter the IP address of the instrument and port 7200 in the connection dialog of
the application software to initiate communication. You can select the instrument
from the list of instruments on the same network as your computer or connect
your computer directly to the instrument Ethernet port.
Port Forwarding
In some network setups it may be necessary to forward communication traffic on a
port from a public IP address to a private IP address to gain access to an instru-
ment. For example, assume you have an analyzer installed in the field and the
instrument is connected to a wireless gateway such as a cellular modem. The instru-
ment will acquire a private IP address from the cellular modem, but this address is
only visible to nodes on the private network. On the other hand, the cellular
modem is assigned a public IP address that can be accessed from any node on the
Internet. For this discussion let’s assume the public address is 166.66.77.88. In
order to connect to the instrument in the private network, a port forwarding rule
must be created in the cellular modem to “forward” all communications on port
7200 coming into the modem to the private IPaddress of the instrument.
