Works fine for me, though the netbsd template script wasn't really
adequate (badly confused prefix allocation and subnet numbering).
This probably only matters if you're getting a /48 from freenet6
and using the tunnel to provide routing to a lan (or group of lans).

That's the way the tspc template scripts set things up.

I do, on that tunnel, and I have no problems like that...
(and I think I saw your name as the contributor of that script).
gif1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
tunnel inet 18.104.22.168 --> 22.214.171.124
inet6 fe80::290:27ff:fe24:c8f4%gif1 -> :: prefixlen 64 scopeid 0x5
inet6 3ffe:b80:2:1a2::2 -> 3ffe:b80:2:1a2::1 prefixlen 64
That's the freenet6 tunnel. Works fine.
What I do on my manually configured tunnel is ...
gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1480
tunnel inet 126.96.36.199 --> 188.8.131.52
inet6 fe80::290:27ff:fe24:c8f4%gif0 -> :: prefixlen 64 scopeid 0x4
inet6 3ffe:8001:2:ffff::102:1 -> :: prefixlen 127
which also works fine. This is on (currently) 1.5W (haven't recompiled
for a few weeks).
