"Most people could do it under load balancing or DMZ but due to many security issues people want to protected it under some source or reverse proxy mean hidden the URL by an alias or wrapper under a different URL.  In this case, people inside the company network will use the real URL but people outside the company will have to use it under a different URL from a restricted network outside the intranet.  DNS mapping can't resolve this issue"

That's my case. Could Jira implement this features as soon as possible?

We have a similar situation as well.  

We do not have a DMZ presence.  Our application is internal. 

However with all the mobile accessibility options today, we wanted our users to be able to respond to tickets outside business hours and off network to update approvals as well as transition issues without having to log onto the company network via VPN or citgo.

We decided to use Azure as a proxy and configure an Enterprise application.

This works somewhat..  as users can access the Azure proxy off network and login with their domain account then Azure passes them inside to the application, which then again prompts for a login, but then we get the gadget errors and marketplace access issues because the Azure proxy URL does not match the base URL.

We don't want a one way only option.  (changing the base URL so everyone has to go through Azure).  It doesn't make sense for on network users to login outside to get back inside.  

We want in office users to be able to access via base URL and the external users access via Azure.

I have tried adding the proxy to the server.xml file or even in java registry parameters but this has no impact.

Microsoft recommends a 

split-brain DNS approach.  Then we can configure 2 Idps (enterprise apps on Azure)

Reference:

https://docs.microsoft.com/en-us/azure/active-directory/manage-apps/application-proxy-configure-custom-domain

 However, we do not want to have to manage external and internal certificates and we don't want a public DNS.

We are also in this situation where we want to setup multiple base url or else option where we can use different url in email notifications.

We would greatly appreciate it there could be multiple URLs, such as an internal URL and an external URL.

It's the problem with hard coded Base URL.  A good system should never have server name/URL ever hard coded anywhere in the system.  I contacted customer support and I was told that if I want to use multiple URLs or Reverse Proxy (different URL) than the internal then Jira is not a tool for me and I should look for something else.  That's not an acceptable answer but well I had no words to say after that.
