Bonjour a tous,
J'ai un petit problème sur la configuration d'un pix 501 sur mon reseau :
Architecture actuelle:
Livebox192.168.1.1<-->192.168.1.141 pix(dmz) 192.168.2.254 <--> reseau -- serveur 1 192.168.2.1
-- serveur 2 192.168.2.2
-- station de travail
Aujourd'hui j'ai une configue où l'ensemble des services dispo depuis internet se trouve sur le serveur 2
L'ensemble de mes station de travail ont accès a internet.
La dmz de la livebox pointe sur l'adresse 192.168.1.101.
Tous se passe bien.
Maintenant j'ai certains service comme le serveur web ou un acès SSH (par exemple 
) qui vont migré de serveur (ils passent donc sur le serveur 1)
et là c'est la cata 
ci dessous ma config actuelle :

Bon, çà fait trois ans que j'y est pas touché et je suis loin d'ête un expert en la matière.
je me suis fait deux ou trois test sans succès en debutant par ajouter
access-list acl-out permit tcp any host 192.168.1.101 eq ssh
static (inside,outside) tcp 192.168.1.101 192.168.2.1 netmask 255.255.255.255 0 0
auquelle le pix m'a repondu : ERROR: duplicate of existing static (ce qui est pas faux ^^)
du coup je me suis lancé dans une refonte de la conf :

et là, bing badaboum, plus rien ne fonctionne, plus rien d'accessible depuis l'exterieur et plus d'accès internet depuis l'interieur 
(j'avais bien switché la dmz de la livebox sur la 192.168.1.141) 
du coup si un utilisateur avreti pouvait jetter un coup d'oeil a ma future config et me dire où je me suis planté, çà serait très gentil de sa part.
