WAN Activation
Activating and accessing the virtual serial port on a NETRS232 device across a WAN can
be done in two different ways, depending on how the NETRS232 device is accessible.
• NETRS232 device is accessible externally – is directly accessible on the Internet.
• NETRS232 device accessible internally – is located behind a gateway or router and is
not directly accessible.
External Configuration
NOTE: All steps assume the Ether-Serial Link has already been configured and is
working on a public IP address.
1. Obtain the IP address of the NETRS232 device
2. Open the embedded web page of the NETRS232 device from your browser by
typing in its IP address in the address bar.
3. Ensure that the port(s) to use WAN activation are configured for “Driver Mode”.
4. Record the TCP port number of the port(s) to be accessed.
5. Open the IP Extender Manager and click on the “WAN Activation” button, located on
the main toolbar. This will open the “WAN Port Settings” window.
6. Enter the IP address of the NETRS232 device and the TCP port number of the first
port you wish to use the WAN activation on, then click OK.
7. This will create a new COM port that you can configure and connect to, as you
would a standard COM port.
8. Repeat for any additional WAN activations you wish to create.
Internal Configuration
NOTE: All steps assume the Ether-Serial Link has already been configured and is
working on a public IP address.
1. Obtain the IP address of the gateway/router that the NETRS232 device is located behind.
2. To configure the NETRS232 device yourself you will need to reconfigure the
gateway/router to allow HTTP port redirection to the NETRS232 device to access the
embedded web page of the NETRS232 device. To do this, please consult either your
system administrator or the technical documentation that accompanied your gateway/
router. If you would rather not turn on HTTP port redirection you can easily have another
user with direct access to the NETRS232 device perform the next three steps.
3. Open the embedded web page of the NETRS232 device from your browser by
typing in its IP address, or the IP address of the gateway/router, in the address bar.
