Конфигурация ProFTPd через SFTP и FTP

У меня есть ProFTPd, который фактически использует протокол FTP, но я также хотел бы использовать SFTP.
Я нашел решение с блоком <VirtualHost>, но оно у меня не работает.

  <IfModule mod_sftp.c>
      <VirtualHost 0.0.0.0>

        TLSEngine          off
        SFTPEngine         on
        Port               2222
        SFTPLog            /var/log/proftpd/sftp.log
        Include            /etc/proftpd/sql.conf

        SFTPHostKey        /etc/ssh/ssh_host_rsa_key
        SFTPHostKey        /etc/ssh/ssh_host_ecdsa_key

        SFTPCompression    delayed
        DefaultRoot        ~
        RequireValidShell  on

     </VirtualHost>
  </IfModule>
