Configuration IKE pour un VPN IPsec...

Pour info, j'ai trouvé de la doc sur nenet que je ne suis pas bien sur de comprendre, à mon niveau :(

http://www.formation.ssi.gouv.fr/stages/documentation/architecture_securisee/vpn.html

http://www.linux-france.org/prj/inetdoc/guides/Advanced-routing-Howto/lartc.ipsec.automati­c.keying.html

Bon... j'ai l'impression que l'échange de clé dynamique (IKE) pour un VPN IPsec, çà à l'air de vous effrayer :((

Alors je continue mes recherches et...
... je me tient au courant ;)

Voilà les dernières news :

quand je lance "racoon -F", j'ai le message d'erreur suivant :
