The world is running out of IP addresses. IPv6 to the rescue! Unfortunately most ISPs dont yet provide IPv6 connectivity. But be sure to ask your provider in order to increase awareness.

In the meantime a number of tunnelling mechanisms have been developed, among them Teredo. Miredo is a GPL implementation of Teredo and it is now available in Portage.

The advantage of Toredo is, that it also works through NAT. Windows Vista and later have Teredo support built-in.

To enable Teredo on Gentoo, simply sync portage and emerge and start miredo:



$ sudo eix-sync

$ sudo emerge -av net-misc/miredo

$ sudo /etc/init.d/miredo start



To start miredo at boot, do



$ sudo rc-update add miredo default
