HowTo Vsftpd
setsebool -P ftpd_use_passive_mode 1
this is up to u.. Permit anonimous users to write with ftp connections:
setsebool -P allow_ftpd_anon_write 1
Create Start Dir  for local account users  ftp_home_dir:
setsebool -P ftp_home_dir 1
make SELinux permit local users acces all FS:
setsebool -P allow_ftpd_full_access 1
Permit vsftpd use Remote CIFS FS.
setsebool -P allow_ftpd_use_cifs 1
setsebool -P allow_ftpd_use_nfs 1

anonymous_enable.
YES or NO is up to you.
anonymous_enable=YES
local_enable.

anon_upload_enable=NO
anon_mkdir_write_enable enable anonimous user to create dir, as usual NO.
anon_mkdir_write_enable=NO
Notes.
to enable  anonimous users upload files to FTP Server leave with YES both Options  /etc/vsftpd/vsftpd.conf   and then create
/var/ftp/incoming,     that belongs to ftp user and group and SELinux   public_content_rw_t.
mkdir /var/ftp/incoming
chown ftp:ftp /var/ftp/incoming
chcon -R -t public_content_rw_t /var/ftp/incoming
Is better if   /var/ftp/incoming  is assigned to separated partition or quota applied to disk to avoid and abuse (attack) that could
fill Server FS.

pasv_min_port=30300
pasv_max_port=30309
