[Ddclient-support] Cannot update local address.

[Alec L. <lea...@gm...>]

Dear list,

I'm trying to update to a non-routable address using "use=if, if=eth0"
against freedns.afraid.org. The relevant part of the logs are below. 
The problem is that despite that eth0 reports 10.136.128.148, ddclient
seemingly uses the external address  XX.20.62.212, the same as would be
used if configured with "use=web".

ddclient version 3.8.2 on debian jessie.

Any clues out there?
