ipv6: how to reconfigure radvd after DSL reconnect?

[dr.nil]

Hi,

I'm trying to get started with ipv6. On my gentoo router box I can start a 6to4 tunnel and ping hosts on the ipv6 network - so far so good. Now I'd like the hosts on my home network (behind the gentoo router box) to use ipv6, too. On the Gentoo IPv6 Router Guide I read that I'd need to run radvd to advertize the routes to the internal network so that I can get a valid ipv6 address for the internal machines.

However, my DSL provider disconnects after 24 hours and upon reconnect I will get a new ipv4 address assigned. This will change the ipv6 address, too and from what I understand so far this requires changes in the radvd configuration.

I did not find any good tips on how to reconfigure radvd - can anyone shed some light, please?

I don't know for other 6to4 providers but with HE your /48 stays the same even if you change you're public IPv4 address. (but you still have to update your HE account with your new IPv4 -- which can be done via a script--)

If you run `/sbin/ip monitor address` it outputs lines every time an interface IP changes - you could use that as the basis to script something when your external IP resets.
