This manual requires a Debian machine to run, minimal system requirements are to have either a public IPv6 or IPv4 addresses.
To use the new features of Tinc 1.1, you have to enable the experimental
package sources. To do so add the following line to /etc/apt/sources.list
deb http://deb.debian.org/debian experimental main
Once added update the repository to allow the installation of the experimental tools.
apt update
Make sure the connection actually works by pinging a website only reachable over IPv6
ping ipv6.ident.me
# or
ping ipv6.google.com
With a public IPv4 it is possible to setup a 6to4 tunnel. To simplify the
setup Debian offers a package to automatically setup the tunnel called
auto6to4. Install it via the following command.
apt install -t experimental auto6to4
Once installed the configuration is done automatically and reboot safe. Test the connection by pinging a website which is only reachable over IPv6
ping ipv6.ident.me
# or
ping ipv6.google.com
To know your new IPv6 address run the following command, requiring curl or
wget installed on the host system.
curl ipv6.ident.me
# or
wget -qO- ipv6.ident.me
To connect the IPv6 server, the one we currently work on, with the IPv6 gateways, the routers which normally would only have IPv4 addresses, the VPN tool tinc is used. It offers a simple way to connect multiple devices to a virtual network. This allows to add IPv6 servers to provide real IPv6 uplink, but also to connect within the virtual network directly between IPv6 gateways with the same IPv6 addresses.
First install the experimental version of tinc which offers new convenience
features like join and invite, more on this in a second.
apt install -t experimental tinc
Once installed we have to setup a new network, first create a folder to store
the tinc setup with the following command.
mkdir -p /etc/tinc/librenet6
All further tinc commands will contain the -n librenet6 argument so the tool
know what network we want to work on.
Tinc is only used to connect all devices in a switch mode. To route the traffic
a dynamic routing protocol is required. To be compatible with earlier setups of
LibreNet6 this setup sticks to babeld.
Install the routing protocol via the following command.
apt install babeld
Now add the following line in /etc/babeld.conf to let the server announce that
it can route IPv6 traffic.
redistribute ip 0::0/0 le 0 allow
Restart the babeld daemon to be sure it loaded the new configuration.
/etc/init.d/babeld restart
# or via systemctl
systemctl restart babeld
