Hello @liammonroe,
We run an Enterprise setup with Oracle (DYN was brought out by Oracle some time ago now).
Having an Enterprise setup allows us to host and manage multiple domains plus subdomains with the advantage of having dynamic domains where required. Where we have Peplink routers acting as “Authoritative DNS” servers, they are still linked back to the Enterprise managed domains.
Here are some of the articles we reference: @Erik_deBie has compiled a guide for setting up DDNS with Peplink/Pepwave equipment that you may find useful
@Alan has compiled a guide for setting up inbound load balancing; this can be done (and we’ve made it work with only Oracle (DYN)) using DDNS through all IPs must be Public-Facing on the WANs as any carrier NATs will prevent this from working).
