στήσιμο vpn server (debian)

[antonis_wrx]

Καλησπέρα.

 

Προσπαθώ να στήσω vpn server σε debian testing έτσι ώστε να έχω ελληνική ip όταν βρίσκομαι Αγγλία για πρόσβαση σε κάποια site. Βρήκα τον παρακάτω οδηγό: http://www.initcron.org/how-tos/howto-setup-vpn-server-on-debian-50-lenny/ και ακολούθησα τις οδηγίες.

 

Το /etc/pptp.conf μου είναι:

 

>localip 192.168.1.2
remoteip 192.168.1.20-29

 

και στο /etc/ppp/pptpd-options άλλαξα τα ms-dns και έβαλα τους dns της forthnet

 

>ms-dns 194.219.227.2
ms-dns 193.92.150.3

 

το /etc/ppp/chap-secrets μου είναι:

 

># Secrets for authentication using CHAP
# client        server  secret                  IP addresses
antonis pptpd   *       *

user    pptpd   pass

 

προσπαθώ να συνδεθώ από το laptop (που έτσι και αλλιώς βρίσκεται στο lan, δεν ξέρω αν αυτό παίζει να δημιουργεί πρόβλημα) με username user και password pass και δεν συνδέεται. Πιο συγκεκριμένα, ο network manager πετάει vpn connection failed.

Άσε στην άκρη το PPTP και στήσε ένα OpenVPN ;-)

[antonis_wrx]

δεν έχω ιδέα από Openvpn. Μέσω lan κατάφερα να συνδεθώ, έπρεπε να ενεργοποιήσω στον client το use point to point encryption (MPPE). Από traceroute φαίνεται ότι το traffic περνάει όντως από τον server. Θα πω σε κανέναν φίλο να δοκιμάσει από έξω να βεβαιωθώ ότι όλα οκ.
