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:
auto 6in4 iface 6in4 inet6 v4tunnel address 2001:08B0:XXXX:0001::1 netmask 124 endpoint 184.108.40.206 ttl 64 up ip link set mtu 1280 dev 6in4 up ip route add default via 2001:08B0:XXXX:0001::2 dev 6in4
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 2001:8b0:7:feed::1 local <ppp0 IPv4 IP> endpoint 220.127.116.11 ttl 64
