tayga - stateless NAT64 daemon
tayga --mktun [OPTION]...
tayga --rmtun [OPTION]...
TAYGA is a stateless NAT64 daemon for Linux. Using the in-kernel TUN
network driver, TAYGA receives IPv4 and IPv6 packets from the host's
network stack, translates them to the other protocol, and then sends
the translated packets back to the host using the same TUN interface.
Translation is compliant with IETF Internet-Draft draft-ietf-behave-
v6v4-xlate-23, and address mapping is performed in accordance with RFC
6052. Optionally, TAYGA may be configured to dynamically map IPv6
hosts to addresses drawn from a configured IPv4 address pool.
As a stateless NAT, TAYGA requires a one-to-one mapping between IPv4
addresses and IPv6 addresses. Mapping multiple IPv6 addresses onto a
single IPv4 address can be achieved by mapping IPv6 addresses to
private IPv4 addresses with TAYGA and then using a stateful NAT44 (such
as the iptables(8) MASQUERADE target) to map the private IPv4 addresses
onto the desired single IPv4 address.
TAYGA's configuration is stored in the tayga.conf(5) file, which is
usually found in /etc/tayga.conf or /usr/local/etc/tayga.conf.
Without the --mktun or --rmtun options, the `tayga` executable runs as
a daemon, translating packets as described above.
The --mktun and --rmtun options instruct TAYGA to create or destroy,
respectively, its configured TUN device as a "persistent" interface and
then immediately exit.
Persistent TUN devices remain present on the host system even when
TAYGA is not running. This allows host-side network parameters and
firewall rules to be configured prior to commencement of packet
translation. This may simplify network configuration on the host; for
example, systems which use a Debian-style /etc/network/interfaces file
may configure TAYGA's TUN device at boot by running `tayga --mktun` as
a "pre-up" command and then configuring the TUN device as any other
