I don't really understand what you mean.
I have a public address, what i can type in at the dlinkddns.com - its something like 89.135.1.1
Of course the NAS have a private address, it's something like 192.168.0.32
If i install the DYN desktop client to a computer, lets say private IP address of the computer 192.168.0.31 - it is able to update the DNS record, and fill the 89.135.1.1 into the database. But the NAS is not able to do same.
Today i updated the firmware on the NAS, downloaded from the dlink, changed to version 1.01.
I am still unable to type manually into the DYN address field, only choose from the dropdown list, but is still don't work. On the list popped a new address, a dlinkddns.com.cn, but is not help either.
Minor change, that now i don't have only the connecting... message, but i get a failure message, like this:
Updated Failure
