10 OpenVPN™ Encryption
The configuration is much more simple, the Router does not need to have a lot of detailed data.
All the different connections required between the Client computer and the NetCom Plus to use
the Serial Device Server are carried via this single OpenVPN™ connection in TCP mode. When
OpenVPN™ is used this way, probably there is no need for an extra protection by encryption.
An encryption of “None” obviously saves computation resources (i.e. performance) on the NetCom
Plus and on the Client computer.
10.5 Reconfigure Virtual Serial Ports for OpenVPN™
It may often happen the NetCom Plus is already installed and tested. In this process typically
the drivers for Virtual Com Ports are also installed, configured and tested. Now the situation may
occur where encryption is a demand. The change of installation is a rather simple process.
First install and test the encrypted connection via OpenVPN™, as described above. Now the
Virtual Com Ports are no longer accessible, because this function is blocked on the IP Address
used on the standard network connection (Ethernet/WLAN). It is only available on the IP Address
provided by OpenVPN™ protocol.
To the driver installation this is the same situation as if the normal IP Address has changed. The
configuration requires a change as documented in section
4.4.5.1
about changed IP Address. Proceed
as described there, and then use the Virtual Com Ports via the encrypted link.
