Ftp – vsftpd: access SFTP on local user without shell access with specific directory

I'm trying to configure vsftpd on my vps in order to access SFTP from Transmit/FileZilla. I've opted for SFTP and the OpenSSL is configured, but I can't seem to manage to add a new user only for FTP-accessing and restrict it for the /home directory only.

Thus, the /home is where I keep my WWW server files and I want a new user to have full access to that directory (chroot).

vsftpd is now capable of allowing the root user to access ftp, but I want to restrict that only for a specific username to allow SFTP accessing.

Some info from vsftpd.conf:

anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
chroot_local_user=YES
chroot_list_file=/etc/vsftpd/chroot_list
local_root=/home

ssl_enable=YES
allow_anon_ssl=NO
force_local_data_ssl=YES
force_local_logins_ssl=YES
ssl_tlsv1=YES
ssl_sslv2=NO
ssl_sslv3=NO
rsa_cert_file=/etc/vsftpd/vsftpd.pem

chroot_list was the file where I added my user "max" to access FTP, but I've removed the user after multiple times where I tried to have it accessing the SFTP.

vsftpd allows a new user to login, but fails when inserting the password. root is ok.

Also, is there any changes to allow specific IP-address to access SFTP?

Thank you.
