My server environment:
I have a website call abc.com. I've created subdomain call demo using Advanced DNS Zone Editor via cPanel and it's point to my static IP 123.123.123.123
demo.abc.com => 123.123.123.123 (winbox installed)
Then I have another local tomcat server with 192.168.1.123 and I have a port forward setup 123.123.123.123:80 into 192.168.1.123
now when I type demo.abc.com
it's going to execute my 192.168.1.123
hosted tomcat website.
Now I need to install SSL on the https://demo.abc.com
which server do I need to use for creating the CSR file ?
123.123.123.123 or 192.168.1.123 ?
