Same story here with Orange in Spain. Fake dual stack through barely-working CG-NAT limited to ports <2000 which many services/devices do not accept and which the router randomly forgot, and no PPTP VPN because the CG-NAT did not support the GRE protocol. Plus the joys of sharing an IP with random strangers, of course. After many clients started complaining they offered us static IPv4 plans (with no IPv6) for free (normally it costs 12€/month), instead of coming up with a better dual stack implementation.
