Requesting a Tunnel/Subnet
1. Sign up with a RIPE/ARIN/etc handle or by using the direct signup
2. After your login at the SixXS Home you can request a tunnel and later a subnet.
Note that providing a link to a XING or LinkedIn profile or providing links to projects you work on can provide extra credits!
[edit] Static Tunnel
There are instructions at Remoteroot.net with example scripts.
This wiki also offers an example IPv6 startup script
Notice that radvd doesn't work with mini version but requires the full version of DD-WRT. Also if you have problems with pinging and SixXS, notice their FAQ message related to this. By default DD-WRT seems to try to masquerade also the IPv6 packets so the following addition to the firewall rule worked for me:
iptables -t nat -D POSTROUTING -o vlan1 -j MASQUERADE
iptables -t nat -I POSTROUTING -p ! ipv6 -o vlan1 -j MASQUERADE

[edit] Install AICCU
1. Install AICCU using ipkg.
# ipkg install http://downloads.openwrt.org/kamikaze/packages/mipsel/aiccu_20070115-1_mipsel.ipk
2. Configure AICCU.
# vi /jffs/etc/aiccu.conf
# AICCU Configuration
# Login information
username
password
# Interface names to use
ipv4_interface vlan1
ipv6_interface sixxs
# The tunnel_id to use
# (only required when there are multiple tunnels in the list)
tunnel_id
# Be verbose?
verbose false
# Daemonize?
daemonize true
# Automatic?
automatic true
Note that if you can't write to /jffs/etc/, you can always store the script in another directory (that of course is persistent otherwise you loose it :) and use eg 'aiccu start /tmp/aiccu.conf' to pick a different configuration file location.
[edit] Automatic start your Tunnel
1. Create a .startup file and make it executable.
# vi /jffs/etc/config/aiccu.startup
#!/bin/sh
/jffs/etc/init.d/S51aiccu start
ip -6 addr add 2001:xxxx:xxx::/64 dev br0 # Edit to your assigned subnet settings. (You have to use /64 here)
# chmod +x /jffs/etc/config/aiccu.startup
2. Adjust the AICCU init script.
# vi /jffs/etc/init.d/S51aiccu
#!/bin/sh
case "$1" in
start)
( while [ `date +%Y` -eq 1970 ]; do
sleep 1
done && /jffs/usr/sbin/aiccu start /jffs/etc/aiccu.conf ) &
;;
stop)
aiccu stop /jffs/etc/aiccu.conf
aiccu stop /jffs/etc/aiccu.conf
;;
restart)
$0 stop
$0 start
;;
*)
echo "Usage: $0 {start|stop|restart}"
exit 1
;;
esac
[edit] Announce your Subnet with radvd
1. Enable radvd at the webinterface of your router (Administration->Management->IPv6 Support)
2. Insert your radvd.conf into the form and save your settings.(You have use the /64 prefix even if you got a /48 subnet)
interface br0
{
AdvSendAdvert on;
prefix 2001:xxxx:xxxx::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};
