One of the concerns that has been raised is the ability to access Exchange Control panel for Exchange 2010 and Exchange Administrative Center for 2013/2016 externally.  Is there a way to prevent external access maybe by limiting the IP ranges that could access it to internal IP ranges only.

For information, the only way to block ECP without resorting to an application aware firewall is to create a second version of the ECP site that is only accessible using an Internal IP address that is assigned as a secondary IP on the Exchange server. Todd's second link explains the process, but be aware that it is a fairly involved process.

Here are some steps for 2013..good luck

1) Add a second IP address to the Exchange 2013 CAS server
   
2) Create the folder in this path %SystemDrive%inetpubwwwroot2
 
3)  Create a second website in IIS pointed to the wwwroot2 folder and call it CustomEAC
 
4) Bind the website on ports 80 and 443 to the new IP address
 
5) Create a new ECP virtual directory using the command
    New-EcpVirtualDirectory -Server ServerName -WebSiteName "CustomEAC" -InternalUrl  
    "https://eac.yourdomain.com/ecp"
   
 6) Create a new OWA virtual directory with this command
     New-OwaVirtualDirectory -Server ServerName -WebSiteName "CustomEAC" -InternalUrl   "https://eac.yourdomain.com/owa"     
   
7) Set the original ECP virtual directory to restrict admin access with this command
   
Set-ECPVirtualDirectory -Identity "MailServerNameecp (default web site)" -AdminEnabled $false
   
8) Edit the IP Address restrictions to only allow access to the EAC website from the internal subnets
 
  Add a host record in DNS for the new EAC URL
