UNIX for Advanced & Expert Users

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 (Linpus) and a Notebook (Ubuntu), they connect 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), so I can access the 3G internet of my provider. It creates a PPP connexion.

So I guess that VPN is well configured, so that my PPP...

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 tunneling.

Has anyone here manage to use a VPN through a Cel connexion with linux ? I challenged several linux's forum, but network's experts are hard to find.

Thanks!

Patrick
