DMZedge Server is installed and running outside the corporate firewall. Cornerstone MFT Server is also installed and running inside the corporate Firewall; The two products are not communicating and end users are unable to connect to the Cornerstone MFT Server through the DMZedge Server interface.

Please make sure you have added the following exceptions to your windows server firewall on your DMZEdge server:

port 45000 for your DMZedge server
port 20/21 for ftp (20 - control, 21 - data)
port 22 for sftp (if using sftp)
port 989/990 for ftps (989 - control, 990 - data)

Make sure your BGR (border gateway router) and Firewall have rules allowing access between your Cornerstone server IP and your DMZedge Server IP on port 45000 and that you have server connectivity. (Can you ping back and forth)?

If all else fails, restart your Cornerstone MFT Server Computer/VM that is connecting to your DMZEdge Server.
