Setup VPN Adapter
SoftEther VPN creates a Virtual Network Adapter (or Virtual NIC) by installing the virtual driver on your system, presenting itself as a hardware network card interface installed on your system. This is the adapter that will “connect” when you connect to VirtuaLAN.
By default, the SoftEther installer will create a basic VPN adapter for you.
If you ever need to specify a network adapter in regards to “on VirtuaLAN”, you should probably be specifying this virtual adapter.
