Na oba računalnika namestite OpenVPN in program za nadzor nad virtualnimi napravami (s katerim kreirate napravo tap).Strežnik SimpleArbiterVPN naj generira skupno skrivnost (*.key), ki jo na VPNCLient uporabite skupaj z konfiguracijsko datoteko za OpenVPN povezavo. Nato poskrbite, da bo VPNClient na navideznem omrežju prek NFS omogočil dostop do imenika /home/test/IME_IMENIKA, pri čemer IME_IMENIKA preberite na SimpleArbiter. V ta imenik skopirajte datoteke, ki so prek SMB dostopne na SimpleArbiter.
