Debian IPv6 Tunnel Config
Draft in progress .....
Configuring your etch host then requires you just to edit /etc/network/interfaces and add the following stanza at the end:
remembering to change the XXXX to whatever value you've been allocated.
After that just type "ifup 6in4" (as root) and your link should be up.
This could be it !! :
auto 6in4 iface 6in4 inet6 v4tunnel address 2001:8b0:XXXX::1 netmask 48 endpoint 18.104.22.168 gateway ::22.214.171.124
