The problem is that many companies have several DNS servers spread out in far-reaching locations, and not all DNS vendors allow access to the logs.

We would like to configure SDWAN for our branch site that only has broadband internet. Because the Public IP changes from time to time, We would like to use FQDN, and so we need to configure DDNS on the internet interface. In order to do that we need to know from which public IP does the PAN use to initiate the SDWAN.
