I recently installed VSFTP with IPKG on my Asus WL500gx running 1.9.2.7-7f Oleg's firmware.
VSFTPD is working fine with my admin account an other accounts (I created home directories in /opt/home/userX with specific permissions).
But, with that configuration, I cannot give access to my external USB harddrive (plugged on the router).
The Fat32 partition is in /tmp/harddisk/, I would like to create a "FTP" directory (/tmp/harddisk/FTP) and difine it as the home directory of all FTP users. I did it in the /etc/passwd file.
But, I cannot set any permissions on the /tmp/harddisk/FTP directory, so users cannot logon on the ftp server.
I would like to get one user with read permissions and another one with read/write permissions inside /tmp/harddisk/FTP, how can I do that? What kind of permissions do I have to set up on /tmp/harddisk/FTP?

Thanks for your help,
