Hi. I'm new to SSL & web development so here's my situation/question :
We have IIS set up on an internal Active Directory domain called "mybiz.local" where we have many Windows Servers (IIS7 hosting intranet apps, SQL, fileservers, etc.) Applications on these servers can get out to the Internet. We have a firewall appliance in place.
Our website "mybiz.com" is hosted on Bluehost, and that website is completely separate from the internal servers at mybiz.local -- mybiz.com is just a few webpages with no data or connectivity to our actual company servers.
We are going to put a .NET application on the mybiz.local IIS server. This app will send and receive credit card transactions to third-party credit card processor "FirstData". FirstData requires we have an SSL cert.
My assumption: Since the SSL cert is for a server with no real web address, will that work? I mean, our IIS server has an internal address (10.9.8.7), and our location has a fixed Internet IP (18.104.22.168) but no registered domain name points to that IP.
Is there an SSL cert that works in this instance?
Do I need to register another domain name to point to our "internal network" ? Or perhaps point a subdomain like "myiis.mybiz.com" to our IP & internal IIS server?
(note: all names and IP addresses have been changed to protect the innocent)
