Entered a Unique Location which it says is Available!
It shows Domain:
Why is it showing 0.0.0.0? It seems that it should display the wan1 public IP address instead.
If I turn the Use Public IP Address - Off it does show the public IP address instead of 0.0.0.0
I guess I don't know what Use Public IP Address means. This seems backwards to me.
Also, when we ping the ddns name, regardless of the Use Public IP Address switch position, we get a successful ping, but it appears to ping to a different public IP address and it will ping successfully even if we turn off Administrative Access: Ping.
I know this is an old post, however I stumbled in to the same thing.
From what I understand, Use Public IP Address is used when you have a NAT between your firewall and the internet. If you have a WAN IP address on the interface you're trying to configure, I believe you leave this disabled.
