255.0.0.0/8 is special and 0.0.0.0/0 is very special. |

255/8 is not globally routed and contains 255.255.255.255 which is used |

as a broadcast address. |

0/0 is functionally equivalent to the default gateway. |

It sounds like you also need to route 10/8 in addition to the |
| 25 |
aforementioned prefixes. |

|
| 27 |
I find it suspect that "b" doesn't work. I wonder if it's related to |
| 28 |
the DNS server that you're querying, specifically if it's internal / |
| 29 |
external and if it's routed through the VPN too. |
