Bonjour tout le monde.
 
Voilà depuis bien longtemps j'essaye de faire un VPN avec un serveur contenant un RAID 5 de quatre disques durs sous DEBIAN.
Jusqu'à présent j'ai réussi à faire le raid avec LVM et tout comme il faut.
J'ai aussi mis en place le VPN (OpenVPN) avec les clés et tout qui va bien.
Et c'est là que j'en viens presque à l'aboutissement d'un looooonnnng travail... Seulement le dossier que je partage depuis mon serveur et auquel j'ai accès via le réseau local n'est pas accessible via la VPN.
De même, je n'ai pas accès à internet quand je suis connecté. Je n'ai pas besoin de rediriger ma connexion internet, j'aimerais partager uniquement le fameux dossier et laisser les clients se connecter à internet via leur propre connexion.
En fait, je veux faire un NAS accessible depuis internet.
 
Ma question est donc double :  
Comment partager mes dossiers sur le réseau VPN ?
Comment laisser les clients aller sur internet via leur propre connexion tout en détectant le partage réseau via VPN ?
 
En fait, je commence à me demander si ce que je compte faire est possible. Je vous avoue que je suis un peu perdu.
 
Bref, je vous remercie d'avance pour votre aide.

Up !
N'hésitez pas à demander s'il faut des précisions.

A mon avis, tu ferais mieux de poser ta question en catégorie OS Alternatif, notamment sur le topic dédié Debian/intégristes barbus

Humm,
 
Des pistes de réflexion peut être :
 
- Pour tes soucis de coupure d'Internet, c'est un souci de routage : sur ton serveur OpenVPN et / ou sur ton client, il ne faut pas que ta route par défaut pointe sur ton tunnel.
 
- Pour ton souci de Samba, y'a plusieurs choses à voir. Le hosts.allow de tes shares, et si samba écoute bien sur ton interface tun : http://openvpn.net/index.php/open- [...] html#samba
 
- Tu pourrais peut être éviter de demander à tes clients d'utiliser un VPN (qui pourrait clasher avec la config de leur LAN que tu ne maitrises pas forcément), et mettre à dispo tes dossiers via Webdav ?

+1 pour ccp6168 sur le soucis de routage et d'adressage.
sinon il y a la methode bourrin, openvpn en mode bridge. tous les clients vpn ont la meme conf reseau que les client sur ton lan. par contre en terme de controle d'acces c'est moyen.

Merci les gars pour vos réponses.
 
Pour ce qui est du Samba, normalement il accepte toutes les connexions. Je sais pas trop comment faire alors tu trouveras le contenu de mon conf à la fin du message, si tu vois une coquille, ça m'intéresse.
 
Pour Webdav, j'ai un pote qui avait essayé, ça avait l'air très lent/instable. faudrait que je réessaye.
mes clients sont les membres de ma famille. C'est moi qui m'occupe de leur PC, hormis du Free wifi, ils ne se connectent que sur mon réseau et au pire ils peuvent mettre en route le VPN uniquement quand ils veulent accéder aux dossiers
 
Comment faire pour que la route par défaut du client ne pointe sur le tunnel ? ou mieux, que le serveur indique directement la bonne route ?
J'ai regardé dans le fichier config d'OpenVPN client mais je n'ai rien trouvé à ce propos.
 
Pour ce qui est de passer en bridge, je suis pas certain que ça arrange la chose vu qu'ils se trouveront complètement sur le réseau local du VPN.
 
Le contenu de mon ssmb.conf:  
#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which  
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic  
# errors.  
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.

#======================= Global Settings =======================
 
[global]
 
## Browsing/Identification ###
 
# Change this to the workgroup/NT-domain name your Samba server will part of
   workgroup = WORKGROUP
   netbios name=DONNEES
# server string is the equivalent of the NT Description field
   server string = %h server
 
# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
#   wins support = no
 
# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
;   wins server = w.x.y.z
 
# This will prevent nmbd to search for NetBIOS names through DNS.
   dns proxy = no
 
# What naming service and in what order should we use to resolve host names
# to IP addresses
;   name resolve order = lmhosts host wins bcast
 
#### Networking ####
 
# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = 127.0.0.0/8 eth0
 
# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
;   bind interfaces only = yes
 
 
 
#### Debugging/Accounting ####
 
# This tells Samba to use a separate log file for each machine
# that connects
   log file = /var/log/samba/log.%m
 
# Cap the size of the individual log files (in KiB).
   max log size = 1000
 
# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
#   syslog only = no
 
# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
   syslog = 0
 
# Do something sensible when Samba crashes: mail the admin a backtrace
   panic action = /usr/share/samba/panic-action %d
 
 
####### Authentication #######
 
# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
#   security = user

# 'encrypt passwords' in the smb.conf(5) manpage before enabling.

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.

   obey pam restrictions = yes
 
# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
   unix password sync = yes
 
# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
   passwd program = /usr/bin/passwd %u
   passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
 
# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.

# to anonymous connections

########## Printing ##########
