Garawa,
This is a bit like "sending you down a rat hole" or telling you that "you can't get there from here." To me it seems clear, Dlink is backing away from the "free" ddns service. This in my mind changes a plus for buying Dlink to a gigantic minus. Dlink has known about DYN DNS going the pay only route for probably a lot longer than the general public. They apparently have made their decision. My guess is that even if your serial number was accepted now, in another 4-5 months, you will get another email from DYN DNS again, telling you that your period of "free" service will soon expire...giving you one option, pay or do without. The real problem is Dlink's products don't give you options for ddns services other than DYN DNS. It is either pay DYN DNS or do without the service. I wish I was wrong and will happily apologize to the folks at Dlink, but I am betting that I will not have to. Dlink could easily put out an official policy on this issue and clarify what products are covered and for how long...but they are letting DYN DNS do their dirty work. If not Dlink, speak up.
