Further information on the port binding: If I run my application as root, all is well. If I run as another user, I get the "Connection reset by peer" message when the device attempts to connect and send a file to the server.
Let me check that I understand you. The device / devices that are attaching to my FTPServer use ports 20 and 21. If I map using IPTables port 20 to 10120 and port 21 to 10121 then I need to bind my server to ports 10120 and 10121. As I stated in the previous post, I cannot bind the server to 10120 and see it appear on a netstat -a command. As for your second point, If I have 10 devices trying to communicate with my FTPServer on ports 10120 and 10121, will they be able to connect simultaneously, or will they have to connect sequentially?
