UPDATE: With a lot of help from my ISP (many thanks), after several tests and experiments, we made some progress:

- the double encapsulation issue was confirmed, they were able to reproduce it
- the issue could be reproduced with a test SIT tunnel. This confirms that H.E. has nothing to
  do with the issue
- the Linux network stack is also not involved, the malformed packets were detected on the wire
- changing the mode from SIT to GRE solves the issue

To summarize:
The issue is happening somewhere during the transit, affected are probably some ADSL customers here in Slovakia (small EU country).
The ADSL is an old technology, but some regions do not have access to better alternatives.
I'm sorry that we could not pinpoint the exact piece of equipment causing the trouble, but the ADSL infrastructure
is operated by a major telco company we didn't contact.

In my case, the problem was solved.

I'm a current Quantum Fiber customer that has a C3510XZ.  Currently I'm trying to complete the setup for IPv6 on it and I got the 6RD functionality to work with the tunnel.  I know it isn't really supported but the tunnel does work and the LAN side is assigning out IPv6 addresses to computers using the routing subnet I gave it.

With that said it also has Dynamic DNS functionality that I can't seem to get to work.  I fill in the custom settings and it keeps saying Not Authorized.  As far as I can tell it is correct but something seems off.

Host name I set to the tunnel ID.  Username is set to shinji and Password is set to the update key.

However when it tries here is what it throws into the log.
Code: [Select]
<13>1 2022-03-31T20:55:31-04:00 user.emerg zcmdModuleCfg - - - zcmdModuleCfg: System: _wanip_auth_check : Last time authentication is Not Accepted. Need to register again.

I just don't know if there is anything I can do to make this work.  I've also thought to use some sort of more lenient script to send it to and act as a relay or forwarder to push to HE automatically but can't find anything to fit the bill.

I can confirm this issue at "Warsaw, PL" tunnel server on freshly created tunnel.

When trying to assign a /48 block to a newly created and working tunnel, I get the error message "Error: /48 assignments are currently unavailable"
Is it a problem, or are the /48 blocks no longer available?

Yes, I did contact via email, and got a reply. The issue is resolved. User error. I had thought I was running traffic through the tunnel, but apparently not, and so the tunnel was automatically deleted.

Your best bet is probably

I logged in last night to change the endpoint IP on my tunnel, as I have done periodically when my ISP changes my dynamic IP. However, my tunnel was not listed. In fact, I think I had two tunnels before, but I was not using one of them. The one I'm interested in, I was using as of yesterday. Why would my tunnel not be there? I searched this forum for "missing tunnel" and "deleted tunnel." Note, I did NOT delete the tunnel, and my data traffic was traversing the tunnel just fine up until yesterday when my IP changed. What to do? I really need the tunnel and the IPv6 address range it allocated to it. The message that says to use the last endpoint to recreate a tunnel doesn't work, because the last endpoint IP is no longer ping-able. But my question is, what happened to the tunnel? I do have the tunnel ID if that will help. Of course I could just create another tunnel (which I did temporarily just to make sure I could), but I really need the old IPv6 address range: I have many of those addresses being used and in fact entered in your FreeDNS.

I just signed one of my zone files, which triggers a script that performs the transfer process of the signed zone from my hidden primary (NSD) to HE's secondary DNS, and then checks that the transfer occurred.

The transfer took place without any issues.

So it seems that HE's DNS is working.

This morning I lost external connectivity to my domain - I use a hidden primary and hurricane as published slaves.

I checked hurricane and it shows last checking of my domain on March 11 (9 days ago).  All of my DNSSEC entries expired at week later (Mar 18).

I deleted the zone and re added it.  If validates fine, but still shows "never checked" and that a zone transfer has not happened.  I see the successful transfer in my Bind logs.  I am not sure what's happening, but it looks like the service is not working.
