I have a couple MX at my corp and they provide HA with different ISPs.
The plan is to provide redundancy for the service at different geographical locations.
I have on-perm and Azure resources and using auto-vpn across the org using MX and vMX to provide access to everything evenly across the network for everyone.
so here I need to implement the most reliable option based on my features to setup the second node as my client VPN server on a MX in different office or on a vMX on Azure.
