IPv6 routing

[Rob Gallagher]

Hi,

I previously had a freebsd 7.0 box set up as an IPv6 router for my
home network, behind a sixxs tunnel. It was running rtadvd to hand out
IPv6 addresses from my sixxs block to the network.

However, after migrating this configuration over to a newly installed
FreeBSD 7.2 box it appears that the machine will no longer route IPv6.
All the correct settings seem to be enabled as described here:
http://www.freebsd.org/doc/en/books/handbook/network-ipv6.html, and
the configurations are identical to the 7.0 box.

The only odd thing I can see is that the machine is not getting an
IPv6 address on the lan-facing interface, which would explain why it
can't route anything. There are no issues with the sixxs tunnel itself
or IPv6 connectivity from the machine; it is also handing out IPv6
addresses to hosts on the network via RAs.

Could there be something I'm missing?
