When I connect my laptop to a remote network and obtain an IPv6 address via a tunnel broker, I would prefer it to be able to use the same IPv6 address as it has at home. The correct solution to this is mobile IPv6. The only information I could find on the Web is somewhat dated. Are the necessary tools and kernel support available in Debian? I'm running Sid. If not, I suppose the other option would be a VPN configuration to my machine at home.
