Thanks for the idea Christoph.
<br />
<br />I had tried some of that last night, but not all. Unfortunately, it didn't shutdown IPV6 right away. A reboot might work, but I've got to wait till tonight to try that.
<br />
<br />And every time I tried to restart SSHD with the "ListenAddress 0.0.0.0" uncommented - it would error with "You've got to specify ports before a ListenAddress". The weird part - I already had a "Port" command in there. I tried adding a second port (I run some of my SSH server on two different ports - so I can get in from the outside while the main router blocks everything on port 22). But that didn't work either. Weird - even with the Port command in there, I'd get the same error.
<br />
<br />Thanks for the try.
<br />
<br />
<br />
<br />Chuck

I've just spent hours trying to disable the IPV6

Did you try this:

As workaround you might want to use a blackhole route for IPv6.

Hope this helps,
