Yeah. I have this in /etc/config/network:

config interface sixxs
        option 'proto' '6in4'
        option 'ifname' 'sixxs'
        option peeraddr '<sixxs ipv4 endpoint>
        option ip6addr '<ipv6 endpoint addr>'
        option ip6prefix '<ipv6 prefix>/48'
        option mtu '1480'
        option ipaddr '<public ipv4 addr as assigned to ge00>'

and each internal interface definition then has a

	option 'ip6assign' '64'

optionally with

	option 'ip6hint '1'

to force the <prefix>:1::/64 subnet to be assigned to the interface.

Isn't that message bus called netlink?

Yeah, I noticed everything is becoming configurable from the config file.

Well, my setup broke when openwrt did the multi-wan stuff. Had to fix
that... :P

Isn't that something you set your editor to do? :P
