[Linpus][Aspire One] VPN (vpnc) is not working with a cel modem (wvdial)
 

Hi all,

it's my first post here. I hope to find someone to help me, I've got a tweaky problem.
I've got a Netbook, it connects fine on any hotspot with a wifi card.
I've configured my VPN, thanks to vpnc. It runs well through my wifi connexion.

I managed to configured my cel modem (wvdial), and I actually write this post from the train on my Netbook.

But, when I try to run my VPN through my 3G cel connexion, I receive the banner of VPN server, and then nothing. I cannot login in SSH on any server of the VPN domain.
But... I checked my /etc/resolv.conf and it has been well replaced to use the primary and secondary DNS of my company. An ifconfig command show me than I send packet but do not receive any on this VPN tunnelling.

Has anyone here manage to use a VPN through a Cel connexion with linux ?

Thanks!
