FreeBSD 10 and IPv6 - something new?

Hi :)
I tried to set up IPv6 on my fbsd FreeBSD, and:
Code: 
ifconfig gif0 create
ifconfig gif0 tunnel XXX.XXX.XX.XX 62.205.132.12
ifconfig gif0 inet6 2a01:d0:ffff:XXX::2 2a01:d0:ffff:XXX::1 prefixlen 128
route -n add -inet6 default 2a01:d0:ffff:XXX::1
ifconfig gif0 up
ifconfig gif0 inet6 2a01:d0:8XXX:: prefixlen 48
ifconfig gif0 inet6 2a01:d0:8XXX::1 prefixlen 128

rc.conf
Code: 
ipv6_enable="YES"
ipv6_activate_all_interfaces="YES"

but IPv6 is not working. On fbsd FreeBSD 8.2 I had no problems.
 
Does it work after you entered those commands? Is this for a particular IPv6 tunnelbroker? Which one?
 
I tried tunnelbroker.net and NetAssist. I tryed to disable my firewall ( packet filter ) but still not working.
 
Leave the last two commands out and test for connectivity then by pinging the remote IPv6 endpoint. Double check that the gif0 interface has no IFDISABLED option set.
 
Code: 
gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280
  options=80000<LINKSTATE>
  tunnel inet XXX.XXX.XX.XX --> 62.205.132.12
  inet6 2a01:d0:ffff:XXX::2 --> 2a01:d0:ffff:XXX::1 prefixlen 128
  inet6 fe80::fad1:11ff:fe3f:f581%gif0 prefixlen 64 scopeid 0x8
  inet6 2a01:d0:XXXX:: prefixlen 48
  inet6 2a01:d0:XXXX::1 prefixlen 128
  nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

You've set the default gateway to yourself, so nothing is ever routed out. Also, don't forget:
Code: 
ipv6_gateway_enable="YES"
To enable IPv6 routing.

As for the default gateway, try this:
Code: 
ipv6_defaultrouter="-iface gif0"
 
Nope...

cat /etc/rc.conf|grep ipv6
Code: 
ipv6_activate_all_interfaces="YES"
ipv6_gateway_enable="YES"
ipv6_defaultrouter="-iface gif0"
ipv6_gateway_enable="YES"

Code: 
PING6(56=40+8+8 bytes) 2a01:d0:ffff:XXX::2 --> 2a01:d0:ffff:XXX::1
^C
