when I try to connect to FTP server as the following commands in debian while ufw is enabled

I got connected successfully

but I can't list the content of directories with the command ls , because it stuck on 150 Opening ASCII mode data connection.

But when I disable the ufw I got it working perfectly.

ftp ServerName.com
Connected to ServerName.com.
220 Microsoft FTP Service
331 Password required
Password:
230 User logged in.
Remote system type is Windows_NT.
ftp> ls
200 EPRT command successful.
150 Opening ASCII mode data connection.

the ufw config as the following

ufw status
Status: active

To                         Action      From
--                         ------      ----
22                         ALLOW       Anywhere
21/tcp                     ALLOW       Anywhere
20/tcp                     ALLOW       Anywhere
22 (v6)                    ALLOW       Anywhere (v6)
21/tcp (v6)                ALLOW       Anywhere (v6)
20/tcp (v6)                ALLOW       Anywhere (v6)

Am I doing any thing wrong !! or what I have to add to the ufw to allow my ftp client to work as expected ?

I am extremly surprised with the low IO performance of Proxmox 6.3.3 , which is in the following configuration and the result Image

• Proxmox 6.3.3
• 512 GB NVMe SSD
• Create new VM content windows server 2019 (the IO test performed inside it)

But I tried to install VMware ESXi 6.7 in the same server to understand what is the source of the issue and to test the IO performance, and I got the following result.

• VMware ESXi 6.7
• 512 GB NVMe SSD
• Create new VM content windows server 2019 (the IO test performed inside it) configured with the same CPU Cors/RAM/Disk Size of the previous test

Is there any thing have to do with Proxmox to improve the IO performance ?

thanks

I have freshly installed Microsoft Hyper-V 2019 (Free), in Remote Datacenter (Different country)

but I can't find a way to upload the ISO files to start installing the Operating Systems

So, How to Copy an ISO file from my computer to Remote Hyper-V 2019 Host (Over the internet) ?
