I have Linux SFTP server where external parties connect to put file operations.
I have different environments internally in my organization. like user access testing, development environment and then production environment.
I have windows servers in each environment. I need following:
1) build ftp server in each environment
2) use web proxy server for connecting from Linux FTP server to my internal FTP server.
3) Do I need SSL certificates, any other things which I am missing
4) how should I configure all three-a general guided approach will be appreciable.
