I am looking for guidance on moving from a single-WAN environment to a Multi-WAN environment.
I currently have one ISP. I host an email server along with an email filter appliance. My MX & Reverse Lookup Record point to the email filter appliance. MX and Reverse Lookup Record (PTR) are hosted with my ISP’s DNS.
My website (www) is hosted with my Domain Registrar. My SPF record is hosted with my domain registrar
I would like to add another ISP to provide redundancy. It was recommended that I look at the PEPLINK to handle the Multi-WAN balancing. I am looking for guidance on the device to use and I’m not sure how to handle email DNS records (MX & PTR).
