RE: ipv6 stateless autoconfiguration failing



The global ipv6 address is lost at about 5 minutes after booting.

There are no ip6tables rules installed.

Router advertisments are received correctly and I found out about this with
two tests:
a) I used whireshark to see the ipv6 packets from where I saw the ra packets
arriving
b) I boot a windows virtual machine via virtualbox using a bridged interface
and the virtual machine got a ipv6 address with no problem.

Is there a way to trigger manually to install a global ipv6 address via
autoconfiguration? I tried ifdown, ifup still with no success.

"A while" being what kind of delay ? Seconds, minutes, hours, days ?

Maybe because the host does not receive router advertisements any more.
Maybe ip6tables rules drop them.
