Postavi dva navidezna računalnika - SimpleArbiter z diska SimpleArbiterVPN ter
VPNClient, ki jima nastavite pravilne mrežne nastavitve (medsebojna povezava in povezava na splet). 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.
