NAT internal IP Address to access an application

[mcoomber]

A client has configured an app on their Server 2022 that needs access from outside the domain. This app is on a physical server and is using port 8080. 

1. How do I NAT the internal IP Address so that users can log on to this web page from outside the office? 
2. How do I configure the subsequent IP Address to go through the Firewall? 
3. If I create a DMZ on the MX and then put this Server 2022 in it, how do I configure the server to be configured internally and externally?
4. Can I configure a proxy server on an MX?
