Is there any possibility to configure ProFTPD that way:
User has read/write FTP access to his home directory
If User connects from inside LAN (e.g. 172.16.0.0) he should have full access (read/write) as usual
If User connects from outside (from internet, or any other network) he should have read only access.
Both cases User should have same login/password
Only one instance of ProFTPD should be active. Instead ProFTPD we can use vsftpd, if it is neccesary.
Is there any ideas to do it?
