Ho installato per prova su un ubuntu 18 virtualizzato su virtualbox openvpn.
nell'immagine su virtualbox ho impostato un ip statico.
Uso una rete con un interfaccoa nat e hostonly.
sull interfaccia hostonly ho impostato l'ip statico cosi:
codice:

ora: ho configurato openvpn su virtualbox.
adesso se imposto sull ubuntu host (il pc che contiene la virtualbox) la connessione a vpn è tutto ok.
https://ibb.co/pJ6p231
i problemi sono:
1)internet quando la vpn è connessa va lentissimo e non capisco perchè
2)adesso che la vpn tra l'host e il guest è in funzione, come faccio a condividere cartelle , vedere hd eccc...?devo creare una rete linux(l'host è un ubuntu 20)?e questa è la cosa principale che non ho capito
3)se digito ifconfig dopo che la vpn è connessa vedo un tun0 è il tunnel criptato?
chiedo scusa se a voi vi sembrano banalità o sciocchezze ma voglio imparare.
ciao.
