I am trying to edit some files on my windows server using Direct FTP. If I connect to the server using just the IP address everything is fine, and the file can be edited and saved remotely on the server. If I connect to the server using IP and some other port number ie: 184.108.40.206:1313 (router would redirect to port 21) the only thing I can do is just navigate through the server folders and open the files for editing(Direct FTP coffeecup). Any changes cannot be saved, I receive error such as the host cannot be found. I prefer to go with the second choice but I have no idea how to fix the error. Any idea would be great.
