I did make it work with DHCP6. The problems are all with my OpenWrt |
| 35 |
router. It is free software and I love it, but it has its |
| 36 |
bu^H^Hquirks. In particular it doesn't seem to be possible to force a |
| 37 |
particular link-local address on the internal interface. Apart from |
| 38 |
that, it needs one crucial bit of configuration that's kind of hidden |
| 39 |
(can't be done via the GUI), to let the router advertisements through. |
