Re: VPN pptpd/pppd
Selon kaya kaya <kaya@kayaweed.net>:
Salut,
As tu désactivé coté WINXP le firewall integré à ta connexion et as tu désactivé
dans les parametres de ta connexion VPN l'option "exiger le cryptage des
données" ( dans l'onglet sécurité ) ???
Il est bien entendu evident que tu n'essaie pas de te connecter en utilisant un
compte UNIX de ta passerelle mais un des comptes définis dans ton chap-secrets
, n'est ce pas???
Momo.
