I'm setting up a web server that has an internal IP address and an external IP address.
e.g. Browsers on the network request mysite.example.com and get 192.168.200 Browsers outside the network request mysite.example.com and get 18.104.22.168
I want to buy and install a certificate for SSL. How can I set this up so that both internal and external traffic is secured with a certificate? Do I need more than one certificate? Is it possible for the certificate to be valid for both IP addresses?
