My domain is cavazos.cc This is a private home setup, not hosted. I lof directly into each of the boxes to do admin tasks.
I have a Synolog router with a static IP address. Access to this router from the internet is via https://cavazos.cc:8000. Connected to this router are three boxes. One Synology NAS with several services running (email, file sharing, etc.) access to this box is via https://cavazos.cc: or https://mail.cavazos.cc depending on the service being accessed. the other two boxes have Ubuntu 16.04 installed running latest Apache and using ports 80 and 443. I use Webmin to manage the linux boxes.
My questions: Can I use a wildcard certificate covering all the *.cavazos.cc addresses? If so, can I have a single certbox running to retrieve the certificate and copy it to the different boxes? Or is it possible to install the certificate only in the router?
Thanks for your help,
