After a while of using the ISP provided 6to4 tunnel, I decided to go back to HE.net and apparently things aren't as smooth as they used to be. I was out for so long, my old tunnel was deleted. So, whatever, I created a new one. Set up the tunnel, configured the router, able to ping the other end of the tunnel, and that's it. Can't get past the first hop.
So I deleted that tunnel, and create another on a different tunnel server. Same issue. So I'm a bit confused now.
Type escape sequence to abort.

I captured some traffic and got some ICMPv6 3 (Time Exceeded) Code 0 (Hop limit in transit) packets. Since I cannot capture on my WAN, and since the source of this ICMPv6 packet was indeed the other side of my tunnel IPv6 address, I'm assuming something's broken on the HE's end.
Suggestions are welcome.
Thanks and regards.
