Please help me understand this issue….
When the Peplink becomes the authoritative DNS server, and inbound load balancing is properly configured, why would anyone need more than one Public IP address (one per ISP or one per WAN connection)?
You only need one Public IP address because you will tell the registrar the Name and IP address of your balance name server and that is really the ONLY IP address(s) you really need! That is, one IP address per ISP/WAN connection. Am I correct?
