Heh, i'll look in the archives... =)

Well, for me it was ages since i used ipv6... So i can't really help. I was more hoping for someone in the same position or someone who'd seen something simular and solved it.
From what i gather, i have done nothing wrong and a forward shouldn't time out. Ie, if it works it should keep working.
It would be really interesting to see what the other end of a ipv6 tunnel sees when it pings, but i don't have the means to test that currently.
