6tunnel allows you to use services provided by IPv6 hosts with IPv4-only applications and vice-versa.
It can bind to any of your IPv4 (default) or IPv6 addresses and forward all data to IPv4 or IPv6 (default) host.
6tunnel can also be used as a tunnel for all other combinations of IPv4 and IPv6 endpoints. If remote host doesn’t have any IPv6 addresses, 6tunnel will use the IPv4 one. In other cases, use -4 parameter which makes IPv4 address the preferred one. For IPv6-to-any tunnels use -6 which makes 6tunnel bind to IPv6 address.
This is free and open source software.
