Configuring the Passive FTP Mode on a Microsoft Azure Instance
By default, Plesk only allows active FTP connections. This may result in customers being unable to connect to the server via FTP. To avoid this, we recommend enabling passive FTP. This topic explains how to enable passive FTP mode in Plesk installed on a Microsoft Azure Platform instance.
To configure passive FTP:
Log in to Microsoft Azure portal.
Go to Virtual machines > click the name of the virtual machine for which you want to configure passive FTP > Networking (under “Settings”).
Click the Add inbound port rule button.
In the “Add inbound security rule” panel, specify the following settings:
- “Service”. Keep the “Custom” value in the drop-down list.
- “Port ranges”. Specify the following port range:
- “Priority”. This value determines the order in which firewall rules are applied. Rules with low priority are applied before rules with high priority. We recommend keeping the automatically assigned Priority value.
- “Name”. Give the rule a recognizable name so you can tell it apart from others.
- (Optional) “Description”. If desired, you can add the description to the rule.
On Plesk for Linux instances, perform the following steps to complete configuring passive FTP:
Log in to your server via SSH as the root user.
/etc/proftpd.d/55-passive-ports.conffile, add the following lines to it, and then save the changes:
<Global> PassivePorts 49152 65535 </Global>
- Run the following command:
systemctl restart xinetd
The required configuration is completed. Now you can use the passive FTP mode on the Microsoft Azure instance.
