Hi all,
It turns out my new ISP, the only one available here, doesn't do IPv6
(yet). So I've been trying to get a tunnel from he.net up.
Here is the relevant snippet from rc.conf:
ipv6_activate_all_interfaces=3D"YES"
# IPv6-over-IPv4 tunnel supplied by he.net; ID 258129
ipv6_network_interfaces=3D"em0"
ifconfig_em0_ipv6=3D"inet6 accept_rtadv"
rtsold_enable=3D"NO"
ipv6addrctl_policy=3D"ipv6_prefer"
cloned_interfaces=3D"gif0"
gifconfig_gif0=3D"50.250.218.161 64.62.134.130"
ifconfig_gif0_ipv6=3D"inet6 2001:470:66:119::2 2001:470:66:119::1
prefixlen 128"
ipv6_defaultrouter=3D"2001:470:66:119::1"
Here is ifconfig -a:

Here is ping6 ipv6.google.com:
PING6(56=3D40+8+8 bytes) 2001:470:66:119::2 --> 2607:f8b0:4010:801::1003

ping6: wrote ipv6.l.google.com 16 chars, ret=3D-1
ping6: sendmsg: Network is down
ping6: wrote ipv6.l.google.com 16 chars, ret=3D-1
When I used the example script that he.net supplies, it brought up
enough IPv6 that I could ping out, and I could ping the two tunnel
endpoints from inside or out. Now, after rebooting, I don't even have
that.
But I also need the routable addresses (I think I got a /64 block)
associated with an interface so they can actually be used. And I don't
see anything on how this is supposed to be done.
Help?
Thanks!
