Hello,
i was just wondering if the Prag Teredo relay is broken - or even active as a teredo relay?!
I can ping facebook or google via my teredo interface just fine, from my traces i can tell that one relay is in London and responding properly.
When i'm trying to ping my 6to4 Networks at home which terminate on the Prag Router aswell, it fails.
The Prag relay does not seem to respond to the bubble packets my client sends as can be seen from the attached screenshot.
