That is great for hardware failures, but what about disasters? I would hate to lose my house to a fire and all the data (including things not replaceable, like family photos) I have on my server at the same time because my primary and backup were both destroyed.
A bit more about mine now that I have a little more time, it’s a VM on vmWare, it has two virtual interfaces, on on my DMZ vlan, and the other is a trunk with the rest of my vlans. With the *sense, I have 2 phisical I terfaces, and then virtual interfaces that correspond to the VLANs. My router is plugged into my switch on an access port for the DMZ, and the ESXi hosts are connected to the switch with VLAN trunks. This allows me to migrate the router to another host for reboots.
I have PF sense virtualized with no issues.
Check out servers ultimate on the app store. They have over 60 services that you can host.
