I believe I have inserted the correct hostname. I signed up at DynDNS and registered xxxxxx.homeip.net
On the DDNS Service page I am inserting:
Select DNS Server (dropdown): http://www.dyndns.com
username: <my login name for DynDNS>
password: <my DynDNS pw>
BUT..now I am able to successfully connect to the NAS via domain name. So the DDNS seems to be working. But if I load the above info into the QNAP DDNS setup page it fails and gives this error I noted in my first post. I guess at this point I am wondering why I need to do this DDNS setup?
And yes I can click on "Get QPKG" but it tells me: "To install QPKG, go to "System Update" and click "Browse…" to select the QPKG file. Then click "Update System".
But I can't seem to find System Update, only Firmware Update.
I also cannot locate the QNAP RSS selection you mention.
Thanks for your help Jason.
