Subj : switching from he.net to 6to4 question
To   : Fidonet.IPV6

Hi all, i thinking on switch the actual he.net tunnel to 6to4 (to avoid 
tunnel latency) and if it are possible to do.

my tunnel have:

address 2001:470:1f1e:4e::2
netmask 64

and use radvd with:

prefix 2001:470:1f1f:4d::1/64

to get my lan with ipv6 too..

this work fine, but bit slow to use ipv6

Now, i test and setup an 6to4 interface in my debian box, and get this 
ipv6 from my internet provider:

6to4      Link encap:IPv6-in-IPv4
           inet6 addr: 2002:be13:ea40::1/16 Scope:Global
           inet6 addr: ::190.19.234.64/96 Scope:Compat

i have some questions:

1) is possible to use this 6to4 and route my lan? if true, wich prefix 
value must be add into radvd?

2) i see that the interface setup i need to mandatory add the local 
public ipv4 address

iface 6to4 inet6 6to4
     local 190.19.234.64

then ifup 6to4 and works fine.

my ipv4 address are dynamic, so i think that must be create the 6to4 
interface manually (scripts that detect the ipv4 and use it) instead of 
/etc/network/interfaces (debian if/up/down). Can you provide some example?


thanks! all
