Problem with nm-pptp

[Lenezir <lenezir frugalware fr>]

Hello everyone.
I need your knownledge !
With a friend we are trying to adapt the module "nm-pptp" of
NetworkManager to the distribution Frugalware.
At first glance, the VPN connection is made, but nothing can happen.
When I go on a website, the browser tries endlessly to join it.
Apparently, the problem comes from the DNS.
In the settings of the wired and VPN, I put the OpenDNS IP and
/etc/resolv.conf contains the correct IP addresses.

Here is the log of NetworkManager when connecting to the VPN :

NetworkManager: <info>  Starting VPN service
