This is a layout of the 'network':
+----------------------------------------------+
|MyBox |

| | - 203.173.130.71/24 -> 203.56.8.99 |
| | - fe80::250:8bff:feb9:2d24%tun0 prefixlen 64 |
| |gif0 tunnel to 206.123.31.114 via tun0 |
| | - 3ffe:b80:2:460::2 prefixlen 128 |
| |vmnet1: |

The symptons were that if I setup a TCP-session, the original message
