Hi Bogdan,

This is what I use on FreeBSD 7.2 i386 with HE tunnel:

rc.conf:
#
# IPv6
#
ipv6_enable="YES"
ipv6_gateway_enable="YES"
cloned_interfaces="gif0"
ipv6_network_interfaces="auto"
ipv6_ifconfig_rl1="2001:470:f8a3:25a::1 prefixlen 64"
ipv6_ifconfig_rl2="2001:470:19:25a:3::1 prefixlen 64"
ipv6_defaultrouter="2001:470:18:25a::1"
ifconfig_gif0="tunnel 219.95.208.53 216.218.221.6 up"
ipv6_ifconfig_gif0="2001:470:18:25a::2 2001:470:18:25a::1 prefixlen 128"
rtadvd_enable="YES"
rtadvd_interfaces="rl1 rl2"
