VPN site to site ASA 5505 probleme connexion

Réseaux & telecom

Salut,
je cherche à créer un VPN site à site avec deux boitiers Cisco ASA 5505. J’ai essayé de préconfigurer en maquette les deux boitiers pour tester le tunnel VPN, mais c’est impossbile de le faire marcher.

J’ai crééle tunnel sur chaque boitier à l’aide du VPN Ipsec Wizard. Les options sont identiques sur les deux boitiers, j’ai aussi entrer les adresses ip des réseaux distants etc.
Je n’ai crée aucune regle de NAT ni de rèles d’accès, tout est en config par défaut.

Je relie donc les deux boitiers par un cable sur leur interface outside (172.16.1.2 et 172.16.1.1). Malheureusement, imposible de monter ce tunnel, je me demande même si il essaye de monter vu que je n’ai aucune stats sur le vpn, ni aucune trace.
Est-ce que j’oublie quelque chose? Une route? une règle ?.

net 192.168.101.0/24 |||| ------>.1—|ASA|----172.16.1.2---------------172.16.1.1----|ASA|—.246<-----------||||net 192.168.1.0/24

Merci

J’ai fait un “show crypto isakmp sa”. Il me met : “There are no isakmp sas”
