NASes may..

Here's the full scoop then: This "NAS" is a tunnel broker. When you
bring up a tunnel, you get an endpoint allocated to you. The tunnel
broker then registers that address against your name in an appropriate
domain. If you are "fred", it will register "fred.domain" for you, with
an forward record mapping the name to the allocated address. It also
registers the allocated address in the appropriate reverse zone, with a
reverse record mapping the address to the name.

I can turn the DDNS updates from the NAS *off*, I just can't fix them so
they are *right*.

So I'm thinking turn off the broken functionality in the NAS, and let
the RADIUS server do the updates. It has all the information it needs
except the nameserver to talk to, which could be configured into this
hypothetical module or script.
