pfSense+ and Zenarmor no more - options?

So due to a change in the latest version of pfSense+, it now no longer allows installation of Zenarmor as a front end for packet filtering. Zenarmor is a great addition and has a solid feature set plus having the option for a paid service for the latest and greatest protection was a bonus.

As this doesn’t look likely to change - what are the options then of using something like OPNSense as a front end with Zenarmor installed which then passes on to pfSense for the rest of the firewalling and routing duties? Something else? If this is possible - how would you set it up?

Was zenarmor a package you can install on pfsense?

Yes. Albeit via the command line - it was a supported install. Controlled via cloud.
