My border gateway has:
ipv6_enable="YES"
ipv6_prefix_tx0="2001:0470:1F00:0820 fd92:7065:0b8e:0000"
ipv6_gateway_enable="YES"
rtadvd_enable="YES"
rtadvd_interfaces="tx0"
I've also use a tunnel broker to get external connectivity
called from /etc/dhclient_exit_hooks
/usr/local/bin/perl -T /etc/tunnelbroker-update-0.07b.pl &
/etc/dhclient_exit_hooks also configures the 6to4 relay so that
traffic to 6to4 addresses gets dumped to IPv4 as soon as possible.
#
# Configure 6 to 4 relay
#
octets=`echo $new_ip_address | sed 's/\./ /g'`
ifconfig stf0 inet6 2002:`printf %02x%02x:%02x%02x $octets`:ffff::1 \
prefixlen 16 alias deprecated link0
route add -inet6 2002:: -prefixlen 16 ::1
route change -inet6 2002:: -prefixlen 16 ::1 -ifp stf0
The laptop has:
ipv6_enable="YES"
Both have firewalls, etc.
