Re: ipv6 / rtadv problem

I have a similar issue. I have:

ifconfig_re0_ipv6="inet6 accept_rtadv"

And after boot, I get:

% ping6 www.google.com
PING6(56=40+8+8 bytes) 2001:470:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX -->
2a00:1450:8005::68
^C
- --- www.l.google.com ping6 statistics ---
5 packets transmitted, 0 packets received, 100.0% packet loss

But, if I ping my gateway, things are fine:

% ping6 2001:470:XXXX:XXXX::1
PING6(56=40+8+8 bytes) 2001:470:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX -->

I didn't have this problem in January.
