As you are on a forceful-disconnect dynamic IP, it will change every 24 hours, you will thus have to reconfigure the tunnel every 24 hours locally and also on the PoP, thus using the webinterface. For this situation, heartbeat does it's job quite well. Unfortunately, (afaik) one can't load extra software onto Airports. As such, you can't use heartbeat, nor AYIYA. Possible Solutions: - ask/beg Apple to implement a heartbeat client - run AICCU on another host behind the Airport. The real solution: unless you have a need to access hosts behind the IPv4 NAT directly (which is actually one of my main reason for liking/using IPv6 ;) there is not much benefit of having IPv6 at a end-user network, especially not in the case where people just surf a bit and read mail, then IPv6 will most likely only hurt due to various strange problems that might occur.
