Good catch; it looks like the pptp plugin just won't handle the VPN
gateway being a hostname, it should try to resolve the hostname to get
the IP address.  NM needs the IP address of your gateway to ensure that
the routing table is set up correctly, and in this case the NM-pptp
plugin is getting it wrong.

What's the output of 'route -n' when this problem occurs?

In any case, an NM-pptp fix is in order here.
