    Accepted Solution

    The problem is with the Router. When you install a ftp server behind a router it works with passive mode and requires an open range of ports. You should limit the passive port range in the Bulletproof FTP server to a small one (1024-1300) and open the same ports on the router. This should work.

    If you still have problems, make sure that the client is using passive mode. Also make sure that the "use site ip for passive mode connections" is checked. This is an option on the FlashFXP client software, but I'm sure it exists on other clients as well.

    The reason for limiting the number of ports is security, of course. You may need to test the server with full load (10 users) and make sure they can all connect and download. If not, you should increase the number of open ports.

    Another security related issue: it can be a very good idea to change the ftp port to a different number than 21, becuase many hackers use this port to try and hack to your pc. Change the ftp port to some unique number.
