Ik heb een server thuis staan die ik via OpenVPN vanaf het werk wil bereiken. OP het werk moet ik langs een proxy server. OpenVPN heeft daar moeite mee, want nadat eerst een connectie lijkt gelegd wordt in de volgende seconde aangegeven dat authenticatie benodigd is.
Ik heb het in de client als volgt ingevuld:
http-proxy xx.xx.xx.xx 8080 file ntlm
en dan heb ik een apart bestandje "file" het volgende ingevuld:
line1: de gebruikersnaam
line2: het wachtwoord
IK heb eerder al een post gezien dat je mogelijk proxifier moet gebruiken om dit op te lossen maar daar wil ik in eerste instantie nog niet mee werken om te voorkomen dat ik problemen krijg met alledaags gebruik van mijn werkgerelateerde applicaties.
Zie bijgaand de configuration file en logging. Iemand goede ideeen?

# On Windows, you might want to rename this #
# file so it has a .ovpn extension #
