The main one at the moment is that I have a dynamic DNS address via noip.com (which I switched to after dyndns.org died). The Station had no problem with this.
Unfortunately the HG659 only lists two DDNS providers, neither of which is noip.com.
Is there some way to add noip.com to the list of providers, or otherwise get the router to do the updates like my old one did? I don't want to have to go back to using a desktop client to update DDNS, that's so 2006.
