Yesterday my tunnel went down and nothing I am doing seems to bring it back up again. The problem occurred yesterday when Comcast renumbered (IPv4) the subnet that I am on. I have reset the IPv4 tunnel termination address, and HE says that it is pingable and reachable. (I can ping4 the tunnel server.) I can ping6 my end of the IPv6 tunnel (IPv6 address of the WAN interface of my router). I can no longer ping6 the IPv6 address of the tunnel server.
So, as I see it, possibilities are:
1. something has changed at HE (I figure this unlikely);
2. Comcast is blocking IPv6 tunneling (they have been deploying native dual-stack and maybe have decided to block v6 in v4 tunneling);
3. Something has changed in my router (m0n0wall -- less likely as I have reconfigured everything, triple checked, and rebooted).
I have reached the end of my troubleshooting wits. If anyone can suggest further steps toward troubleshooting I would appreciate it. Thanks in advance.

What's the IP address of your end of the tunnel?
You can also email ipv6@he.net. It's possible your old IP address is stuck in the config or something

Thank you. I will try that too. (Was looking for a direct email address to HE but didn't find it.)
Appreciate your response.

I can't ping your end of the tunnel, so the tunnel isn't up (as you said)
I can ping the HE side without any problems.
Good luck

I sent email to ipv6@he.net as you suggested and, >POOF<, all fixed. I suspect that your supposition was correct. Thank you for your assistance.
