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.

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.
Try this as URL "ipv4.tunnelbroker.net/nic/update?hostname=<id>" where you replace "<id>" with your tunnel id.
