Hello good people!
I just recently subscribed to Cloudflare to manage all my servers and I would like to get some advice from experienced people here! I have been reading Cloudflare documentation, and some youtube videos but have not found the proper way to secure all my servers behind the same domain.
First I will explain how my setup is:
I have two office servers, both of them hosting some websites set on different networks, one of them is with ubuntu 14, and the other one is a host for Hyper V with two virtual machines each one with IIS 8, and both of them set to port 80 and 443, one of those I access it with the default 80:443 ports and the other one with custom port forwarding to 80 and 443. These servers are accessed by employees, and by clients.
Also, I have the main business website hosted at WIX.
I have CNAME records set for every website.
So my questions are:
a) How can I properly secure all these servers with Full (non strict) encryption mode?
b) Can I use the same Origin CA cert for every server? and do I have to set all the CNAME records to the cert? or just with the wildcard?
c)How do I setup Cloudflare to access the IIS set to custom external port with port forwarding, I can not reach it with http(s)://cname.mywebsite.com:5555
I hope I explained myself fine, sorry if not! English is not my native language.
