I'm using a v6->v4 tunnel broker so my ISP is out the loop, what's more, |

It looks as if the problem may be related to MTUs. I did a bit of |

jiggery-pokery with MTUs, setting the MTU for the IF on my desktop |

appears that the problem is solved for now, at least. |

I've seen network problems before with MTU issues, especially where UDP |

packets are involved, as they may be with the tunnel broker. |
