Notable largely for the complete lack of a default route.

Consider setting your gateway explicitly instead of depending on router


or whatever that address is.  Otherwise you'll need to figure out what's
broken with router advertisements on your network.  My quick read of
your ipf.rules file leads me to believe that you're allowing icmp6
router advertisements in

Are you logging advertisements based on that?  If you don't see them,
you probably need to figure out what's up with your gateway device.

As a quick check, you can also override the routing table with the -g
option to ping6.
