مشکل با Data Socket در FTP

سلام دوستان
من روی سرور از روترمیکروتیک استفاده کردم
برای FTP هم پورت 21 باز هست و بقیه پورت ها بسته...

زمان اتصال با برنامه CuteFTP جز اینکه به پورت 21 وصل میشه به "FTP data socket" هم نیاز داره که چون پورت ها رو بستم نمیشه وصل شد کامل
آیا راهی هست که فقط از 21 استفاده بشه یا اون "FTP data socket" از پورتی که ما تعیین کردیم استفاده کنه و Random برای خودش پورت انتخاب نکنه؟
123.456.789.111 : آی.پی سرور مثال هست

1) Verify that the destination IP address is correct.
2) Increase the connection timeout threshold under Global Settings | Connection.
3) Switch to the opposite data connection type (PASV or PORT) under Site  Settings | Type tab.
4) Verify that the problem is not local by trying to connect to an alternate  server.
5) If a server name was used, verify it resolves to the correct address.
6) If using a local server table for server name resolution, check to see that  it doesn't resolve to an obsolete address.
7) Try pinging the address.
8) If you are using a router, verify the router is up and running (check by  pinging it and then ping an address outside of the router).
9) Do a traceroute to the destination to verify all routers along the connection  path are operational.
10) Verify that your subnet mask is setup properly.
11) Verify that your local software or hardware firewall is not blocking  outbound connections originating from CuteFTP.
12) Verify that your anti-virus software is not at fault (try disabling it).

UP

FTP نیاز به دو Port داره.

در تنظیمات FTP Server میتونید برای حالت Passive برای Data Port یک Range تعریف کنید و در Firewall اون Range رو باز کنید.

پروتکل FTP چه در حالت active و چه در حالت passive به 2 تا پورت احتیاج داره.
