Thanks for the follow up. So, in recap, I'll use my central CA to create SSL PEM certs to issue to each endpoint for the ptp and then setup IKEv2 for with EAP for the workstations. It sounds reasonable. I've been looking through some of the additional docs (there's a lot to take in) for each of the configurations, so I'll probably try this weekend to see if I can at least get the ptp networks up and running first.

Again, Thanks
