ipv6tun IPv6 Tunnel Broker daemon for Mac OS X Why? Because the Internet is running out of room, we will see more and more services only available through IPv6. An IPv6 tunnel makes it possible to access the IPv6 side of the Internet when the current internet service provider doesn't come with native support (yet?). This project aims to make it easier to setup and use such tunnel on Mac OS X. Right now, tunnels were only tested with Hurricane Electric's Tunnel Broker service, but it should work with other providers too. FAQ What kind of tunnel is this? This project makes creates 6in4 tunnels using gif interfaces (which support is built-in OSX). Install In the project directory: $ sudo make install This copies the ipv6tun executable to /usr/local and a configuration file at /usr/local/etc/ipv6tun.conf. It also take care of registering with the system in order to keep the tunnel working in case of network change: Wi-Fi toggle Ethernet (un)plug DHCP lease expiry etc Configuration and usage The configuration is done with a single configuration file. Relevant information should be provided by your tunnel broker. # In /usr/local/etc/ipv6tun.conf ipv6_wan_address=<put_here_the_client_ipv6_address> ipv6_default_route=<put_here_the_server_ipv6_address> remote_ipv4_address=<put_here_the_server_ipv4_address> tunnelbroker_update_enabled=no # Put to "yes" to enable feature tunnelbroker_tunnel_id=000000 tunnelbroker_account_name=somebody tunnelbroker_update_key=secret Once configuration is done tunnel can be made up or down with respectively $ ipv6tun up or $ ipv6tun down. Tunnel status persist across reboots. Public client address update ipv6tun can take care of updating the client side IPv4 address of the tunnel on the provider side. This feature is optional and only supported with Hurricane Electric at the moment. Support for SixXS is being considered.
