Hmmm I checked for unread messages prior to doing anything, but nothing came up, I should have looked here first.
I think you missed the point about my previous post about the IPs, the 7 and 8 aren't in the same /64 subnet, it's kind of confusing, but in any case everything seems to be working now.
The IPs will always be in different /64s, is my point. This is not new or strange. We use different allocations for the point-to-point and routed. The difference is that we stopped allocating them in the 1f## range. Look at other tunnels you have and you'll see them in different ranges.
