The problem is there are no Teredo relays reachable by the clients you contact. There used to be a global BGP anycast Teredo relay prefix advertised by a South Korean ISP, but maybe its not accepting your traffic.
Teredo works, if you ping6 a machine, which is known to have a route to a working Teredo relay, like the IPv6 machines basile.via.ecp.fr zen.via.ecp.fr BTW, I don't understand why Microsoft, Cisco & other big guys interested in IPv6 don't use this obvious marketing opportunity to advertise public Teredo relay BGP anycast prefixes. Any possible tarffic cost is bound to be a short term problem, and will get easier by each new anycast server deployement. You know, for a period one South Korean Teredo relay router served the whole world... Heck, it would be a reasonable requirement set by RIPE, ARIN & others, that to give an IPv6 address block for an AS, it should be required to be running a Teredo relay and a 6to4 relay for their own customers at least, if not in a publicly accessible way. If someone at the IANA/IETF lobbies insists it would be too costly, let's just say that the amount of handwith required to handle would not be specified... --------------------------------------------------------------------- The IPv6 Users Mailing List Unsubscribe by sending "unsubscribe users" to [EMAIL PROTECTED]
