Got something for you to have a look at. I'll be on IRC tomorrow morning, DHCPDv6 needed a rethink. :) |

Builds upon the 6rd routing fixes discussed in https://forum.opnsense.org/index.php?topic=20260.0 Instead of setting the calculated /64 subnet length on the _stf interface, I set the original ISP provided subnet length. And change the gateway to be inside the ISP provided prefix instead of the calculated /64. wan address will still be the same but the wider subnet solves any routing issues with single /64 prefixes (cherry picked from commit 866e8f2)
