SixXS (Six Access) is a free, non-profit, non-cost service for Local Internet Registries (LIR's) and endusers. The main target is to create a common portal to help company engineers find their way with IPv6 networks deploying IPv6 to their customers in a rapid and controllable fashion. To reach these targets we are providing a whitelabel IPv6 Tunnel Broker and Ghost Route Hunter, an IPv6 route monitoring tool and various other services to help out where needed.

sslh accepts connections on specified ports, and forwards them further based on tests performed on the first data packet sent by the remote client.
