Before that they used our (Tele2) 6to4 relays in Amsterdam and Paris. I think this was discussed here 1-2 years back.

I couldn't find it, but <http://gpshead.blogspot.com/2009/01/consumer-router-ipv6-firewall-fail.html> says the same thing.

I urge more people to look up what 6to4 relays you're using and set up your own if needed. People *are* using it and you not doing it is making things worse for your customers. Yes, 6to4 is generally bad but it's out there. Everybody needs to think about it.
