The pptp connection works reliably if I enter one single of the many ip addresses of the ipredator vpn gateway instead of the dns name.

vpn.ipredator.se resolves to quite a lot of ip addresses. So either network-manager-pptp has a general bug with the dns resolver, or it has problems with multi homed hosts.

$ dig @8.8.8.8 vpn.ipredator.se
