IPv6 tunnel broker setup
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 haveand installed.
/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 you can add a dispatcher script for the NetworkManager, so it will start whenever your network is ready. Note that enabling the service via systemd will not work, as the network will not be ready on boot. Please see FS#38221 for more details.

Setting up Hurricane Electric tunnel
Create the following systemd unit, replacing bold text with the IP addresses you got from HE:
[Unit] Description=he.net IPv6 tunnel After=network.target [Service] Type=oneshot RemainAfterExit=yes ExecStart=/usr/bin/ip tunnel add he-ipv6 mode sit remote Server_IPv4_Address local Client_IPv4_Address ttl 255 ExecStart=/usr/bin/ip link set he-ipv6 up mtu 1480 ExecStart=/usr/bin/ip addr add Client_IPv6_Address dev he-ipv6 ExecStart=/usr/bin/ip -6 route add ::/0 dev he-ipv6 ExecStop=/usr/bin/ip -6 route del ::/0 dev he-ipv6 ExecStop=/usr/bin/ip link set he-ipv6 down ExecStop=/usr/bin/ip tunnel del he-ipv6 [Install] WantedBy=multi-user.target
If systemd-networkd handles your network connections, it's probably a better idea to let it handle tunnel broker too (instead of using a
[Match] [NetDev] Name=he-ipv6 Kind=sit MTUBytes=1480 [Tunnel] Local=<local IPv4> Remote=<tunnel endpoint> TTL=255
[Match] Name=he-ipv6 [Network] Address=<local IPv6> Gateway=<IPv6 gateway> DNS=2001:4860:4860::8888 DNS=2001:4860:4860::8844 [Route] Destination=::/0
And, add this line to
[Network] section of your default Internet connection
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:
