4.9.1 Port forwarding
Note
Note
Port forwarding enables you to set up a server connected to the terminal while the
terminal is in Router mode. Without port forwarding it would not be possible to
contact the server from the Internet. We recommend using a static public IP address
for the terminal in order to provide easy access to the terminal. To use the static IP
address, it must be included in your subscription and you must set the APN source to
SIM default. For details, see To change the APN for a connection package on page 4-6.
The following example shows how to allow Internet access to a mail server (smtp)
connected to the terminal. The mail server in this example has the IP address
192.168.0.100.
1. From the Control panel
2. Select + Forward port to add a new port forwarding.
3. Select Active to activate the port forwarding.
4. Type in the Incoming port start and the Incoming port end.
This is the range of port numbers on the EXPLORER 540 for which incoming traffic
to the EXPLORER 540 will be forwarded.
5. Type in the Destination IP address, which in this example is the IP address of the
mail server: 192.168.0.100.
This is the IP address to which the incoming traffic is forwarded.
6. Type in the Destination port start and the Destination port end.
This is the range of port numbers at the server, to which the incoming traffic will be
forwarded. If only a single port is used, type the same port for Destination port
start and Destination port end.
7. Click Save.
When you have activated a data connection, you can now access the server from the
Internet, using the external IP address of the terminal. If you are using the web
interface, you can see the external IP address in the tile with the data connection you
have started. For information on how to activate your data connection, see To start
and stop data connections on page 3-25.
To add more ports for port forwarding, select + Forward port again and repeat the
procedure above.
As an alternative to Port forwarding, you may use a dedicated connection, see To set
up dedicated connections on page 4-9.

Make the port forwarding configuration before starting the data session.
Normal port forwarding configuration is ignored in Cellular modem preferred
(PRISM) mode and External modem preferred (PRISM) mode because all
connected units are directly accessible by PRISM port forwarding.
