I run multiple domains as virtual servers on a NAS on my home network and 4 of these domains are accessible from the internet through my firewall. My dynamic DNS entries are managed by an external provider.
I want to have 4 different certs for the different domains running on an NGINX reverse proxy funneling traffic to 4 virtual servers on a different machine.
What is the best method. One cert for multiple domains?? Or different ones
Second, the challenge question to prove ownership of domain… Do I need to set up text files once the challenge is issued on each of the virtual servers?? Or do I pick the DNS challenge and create new DNS entries for each of the domains on my dynamic dns providers??
Any pointers appreciated
