Hello everyone,  I just had to get rid of a bad DIR-825 that I replaced a trusty old DIR-655 with and now I'm back.  Anyhow, I can't seem to make the DDNS setting stick in the router.  All of the information is correct, but it doesn't seem to want to login.  When I click the enable check box, it tries connecting and then greys out and doesn't connect. Any thoughts would be appreciated.
