So, you are saying IC2 is not required to use sequential DDNS (in a non-speedfusion environment)?
All we want (from my 2016 message …):
(One DDNS for both WAN - #12 by Rick-DC)
TK: Actually, our experience with DDNS is excellent. Our DDNS provider has been extremely reliable. All we need to do is have the Balance router send an update the DDNS when the favored/priority/best WAN changes. The DDNS would not point to a lower capacity/high latency WAN until the “main” one fails .
