[RESOLU]pfSense 2.0RC1 ipsec/mobile client avec shrew



  • Bonjour à tous,

    je rencontre des soucis avec ipsec. Le tunnel ne se monte pas (echec phase 1). J'ai suivi le même type de configuration que ce tuto : http://doc.pfsense.org/index.php/IPsec_Road_Warrior/Mobile_Client_How-To

    J'ai testé avec openvpn et le tunnel se monte sans probleme.
    Quelqu'un aurait-il réussi ? Si oui je suis preneur.

    client mobile –----->>>WAN (modem @ip public fixe) pfsense ------>>>> LAN

    Dans les règles du pare-feu j'ai ouvert le port 500(ISAKMP) sur la parti ipsec et le port 500(ISAKMP) et 4500(IPsec NAT-T) sur le WAN.

    Et voici un extrait de mes logs :```

    Merci pour votre aide.


  • problème résolu.

    La réponse était dans les logs….

    Unknown Gateway/Dynamic. Et comme j'ai 2 liens WAN dont la passerelle par défaut était la WAN1 que j'ai coupé pour effectuer mes test. J'ai donc mis WAN2 comme passerelle par défaut dans system->routing.



  • Commençons par les vérifications de base :
    Vous utilisez une PSK ou des certificats ?
    Y a t il des erreurs sur l'interface Wan ?
    Les logs de Pfsense permettent ils de vous voir arriver sur l'interface wan ?

    Edit : message posté sans avoir vu le précédent.



  • J'utilise PSK.
    Je ne pense qu'il y est d'erreur sur l'interface WAN…
    Et en regardant mes logs on voir bien que du trafic arrive sur le WAN.

    Mais c'est bon, maintenant sa fonctionne. L’erreur se situé par rapport à ma passerelle par défaut.
