透過C# FtpClient 函式庫上傳CSV檔案到遠端FTP空間

FtpClient client = new FtpClient();
client.Host = "xx.xx.xx.xx";
client.Credentials = new NetworkCredential(UserName, Password);
client.SslProtocols = System.Security.Authentication.SslProtocols.Tls12;

client.Connect();
if (client.IsConnected)
{
   Console.WriteLine("Connected");
   client.DataConnectionEncryption = true;
   var result = client.GetFilePermissions("/Test.txt");
   client.UploadFile(@"C:\Users\Desktop\Test.txt", "/Test.txt");
}
else
{
   Console.WriteLine("No Connetion");
}

但當程式到了以下程式碼
client.GetFilePermissions("/Test.txt");

會出現以下錯誤

Unable to read data from the transport connection: An attempt was made to access a socket in a way forbidden by its access permissions.

但當我防火牆全關時候，檔案是可以順利上傳遠端FTP的

目前防火牆設定例外
(Inbound)
Local port 3072,80,20,21,1023
Remote port 3072,80,20,21,1023

(Outbound)
Local port 3072,80,20,21,1023
Remote port 3072,80,20,21,1023

因此想問的是防火牆的inbound 或outbound要怎麼設定才能讓上傳檔案到遠端的FTP
