Our ISP performs native IPv6 and a router that fully support it (AVM FRITZ!Box 7370, No tunneling at all) However, after some time all IPv6 addresses become "deprecated" wich make using IPv6 unreliable. How to never get an IPv6 address "deprecated". Any help available? Kind regards, Ruud UphoffGrtz, Ruud

I suspect that this is a firmware issue in the router. Without additional info as to your ipconfig or details on how the router is actually configured, this is touch to diagnose. I have seen similar issues caused by bad tables - router firmware.
