Hurricane Electric offers a free tunnel broker service that is relatively painless to use under Arch if you wish to add IPv6 connectivity to an IPv4-only host.

These instructions work for SixXS tunnels as well.

Registering for a tunnel

It is not that hard to do. Feel free to fill in the directions here if something seems tricky, but otherwise just go the tunnel broker site and complete the registration.

Setting up SiXxs tunnel

First, you need to have aiccu, radvd and iproute2 installed.

Now edit /etc/aiccu.conf and fill in your data. If you have several tunnels, you need to also supplement the tunnel_id option in the file. The following is an example for a dynamic ayiay tunnel.

username <username>
password <password>
protocol tic
server tic.sixxs.net
ipv6_interface sixxs
automatic true
requiretls true
pidfile /var/run/aiccu.pid
defaultroute true
makebeats true
behindnat true

Test the configuration now with:

# systemctl start aiccu

If it works, enable it:

# systemctl enable aiccu

Configuring radvd and LAN side IP of the router: See Router.


Systemd script

/etc/systemd/system/he-ipv6.service
[Unit]
Description=he.net IPv6 tunnel
After=network.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/sbin/ip tunnel add he-ipv6 mode sit remote 209.51.161.14 local <local IPv4> ttl 255
ExecStart=/sbin/ip link set he-ipv6 up mtu 1480
ExecStart=/sbin/ip addr add ''local_IPv6''/64 dev he-ipv6
ExecStart=/sbin/ip -6 route add ::/0 dev he-ipv6
ExecStop=/sbin/ip -6 route del ::/0 dev he-ipv6
ExecStop=/sbin/ip link set he-ipv6 down
ExecStop=/sbin/ip tunnel del he-ipv6

[Install]
WantedBy=multi-user.target

Using the tunneling with dynamic IPv4 IP

The simplest way of using tunelling with a dynamic IPv4 IP is to set up a cronjob that is going to periodically update your current address. To do that open crontab -e and add, in a new line:

*/10 * * * * wget -O /dev/null https://USERNAME:PASSWORD@ipv4.tunnelbroker.net/ipv4_end.php?tid=TUNNELID >> /dev/null 2>&1

Which should also make wget quiet and not bothering you with emails about its activity. Please replace USERNAME, PASSWORD and TUNNELID by the details of your account and tunnel. I would recommend running the command on its own first, to check if it works. To do that run:

wget https://USERNAME:PASSWORD@ipv4.tunnelbroker.net/ipv4_end.php?tid=TUNNELID
