[VPN] Utiliser Cisco sur Vista

Bonjour,

Je suis dans une résidence universitaire utilisant un VPN et j'ai donc besoin d'utiliser le client CISCO pour me connecter.
Je suis sur windows VISTA 64bits et j'utilise CISCO v5.0.07.0290
Quand je lance la connection j'obtient cette erreur :


Error 403: Unable to contact the security gateway



J'ai le log suivant pour plus de détails :
