Installed is also a bunch of files and programs in your program files 
folder, and a new service for OpenVPN™. This service is configured to 
start “Manually”, and is covered in a later section.

The next task is to configure the NetCom for encrypted communication. 
It is assumed the NetCom is already configured for the network. At this 
step it does not matter if the communication is via Ethernet (Cable) or 
via WLAN antenna (Wireless), as is mentioned above. Open your web 
browser, and go to the address of the NetCom Server. Select the 
“Tools” page, and activate the option of “DebugLog” (5.1.3.7 above). 
This is not required for operation, but will help to see what happens on 
the NetCom. 
Next go to the “Server Configuration” page, and scroll to the section of 
OpenVPN (5.1.1.4 above). Check all parameters to be the same as in 
the Image 21 above. 
Open the “Configuration-Settings of the Encryption-Key” (Image 23), 
and click the “Show” button to display the current key. Save the key in 
OpenVPN config, in your program files folder. Use the suggested name 
of »storedkey.cfg«. Select the Encryption by “AES-256-CBC”, which is 
the default. 
Warning: When the NetCom is configured for OpenVPN™ operation, 
there is no access or configuration without the valid key. Be sure to 
have all information saved to your system, before enabling the 
encryption. Otherwise the only way back to normal access is by setting 
the “Factory Defaults”. 
Then enable the Logging for NetComs OpenVPN function. Save all 
changes to the NetCom. Note: OpenVPN function is not enabled so far. 
This final step is done when everything else is ready, including the 
configuration of OpenVPN™.

OpenVPN may be started in several ways. One option is the command 
line, which has the most flexibility. The next option is to use the 
Context-Menu of the configuration file, and finally the installed service 
for OpenVPN will also open the connection. All three methods are 
covered in short.
