Hello,

Have three nodes with IPv6, 1- Teredo, 1 - Tunnel Broker 6in4, 1 - ISP Native IPv6.

From the TunnelBroker 6in4 can establish an ssh connection to the node using Teredo.

From the ISP to the Teredo node is not accessible.

In looking at the traceroute from the ISP IPv6 to the Teredo node it looks like the traffic gets dropped at a HE.net router.

$ traceroute6 2001:0:53aa:64c:49:7c32:b05f:XXXX
traceroute to 2001:0:53aa:64c:49:7c32:b05f:XXXX (2001:0:53aa:64c:49:7c32:b05f:XXXX), 30 hops max, 80 byte packets
