Hi Paul, thanks for responding.

I actually quoted the ticket earlier in this thread, but it says
no more than what you said.

Do you have access to the Hetzner "robot" for this container?
Hetzner by default assigns each physical host a 64-block
of IPv6 addresses, and a specific IPv6 address to use as the
gateway. Then we would need to know how the LAN for the
VMs inside the container is configured. I am clueless
about how all those things work in IPv6.

Ian's code from interfaces that you quoted is probably
handling all of those things, but I'm guessing that the actual
addresses were never updated when we moved to the
new container.

Also, all the things Ian is doing manually probably can
be done much more simply in a modern OS.

Then again, this isn't exactly a modern OS. It's
Debian Lenny, which has been unsupported for almost
2.5 years. Weren't we going to update this server to
Ubuntu LTS so that it would quit going EOL on us so
often?

Thanks,
YItz
