Hi,
We use FTP Passive mode so it seems FTP will connect using a random port higher than 1024 and lower than 65535 This port is chosen by the FTP server i.e. your server and you can change the FTP server settings to choose which ports to allow. Once you have decided which ports to allow please open those ports in the Firewall. ----------------------- Webuzo - Multi User Hosting Control Panel AMPPS - Best WordPress/PHP/MySQL development tool |

To be more clear if you using Active FTP or Passive FTP mode
If its Active FTP From the server-side firewall's standpoint, to support active mode FTP the following communication channels need to be opened: FTP server's port 21 from anywhere (Client initiates connection) FTP server's port 21 to ports > 1023 (Server responds to client's control port) FTP server's port 20 to ports > 1023 (Server initiates data connection to client's data port) FTP server's port 20 from ports > 1023 (Client sends ACKs to server's data port) If its Passive rom the server-side firewall's standpoint, to support passive mode FTP the following communication channels need to be opened: FTP server's port 21 from anywhere (Client initiates connection) FTP server's port 21 to ports > 1023 (Server responds to client's control port) FTP server's ports > 1023 from anywhere (Client initiates data connection to random port specified by server) FTP server's ports > 1023 to remote ports > 1023 (Server sends ACKs (and data) to client's data port) to by in short the following chart should help admins remember how each FTP mode works: Active FTP : command : client >1023 -> server 21 data : client >1023 <- server 20 Passive FTP : command : client >1023 -> server 21 data : client >1024 -> server >1023 this port value will start from 1023 and lower than 65535 ----------------------- Hostripples Webhost Softaculous Hosting |
