[Typo3-linux] htaccess and directories

[Patxi Goitia]

Hi, I'm trying to configure the htaccess I have in the root of my site 
to restrict access to several directories. I want to do that by using 
allow / deny to give access to those directories only to LAN ips.

Until now, I had a htaccess file in each directory.

I want to do all this job only from 1 htacces file, but I'm unable to 
find the way to do it...

Any idea ?

TIA
