I´m looking for a way to update more then one dyndns accounts automatic (needed for hostheader resolving at local web services) Nvram seems to support this (ddns_xxx_2) but, how to use?
I don't know the answer but here's the results of a brief test. First I entered the following info into the DDNS GUI: Then I checked the nvram variables and saw: Obviously the GUI doesn't use the ddns_xxx_2 variables so while I have no idea if it would work maybe you could simply try manually assigning values to the ddns_xxx_2 variables? BTW all the ddns_xxx_buf variables appear to store the previous value you entered into the GUI. For example, configure DDNS via the GUI and Save. Then configure different values & save again. Looking at nvram you'll notice that all the ddns_xxx_buf variables hold the values you saved the 1st time... Good luck and let us know how it goes!
