TAYGA is an out-of-kernel stateless NAT64 implementation for Linux that uses the TUN driver to exchange IPv4 and IPv6 packets with the kernel. It is intended to provide production-quality NAT64 service for networks where dedicated NAT64 hardware would be overkill. TAYGA needs no kernel patches or out-of-tree modules, and it is compatible with all 2.4 and 2.6 kernels.
