Hi Hanane,
This is possible like you say, you'll have to present the repository to the outside world through a DMZ or some kind of port forwarding.
In terms of licensing, every user that access's Laserfiche must have a license of some sort (with the exception of Weblink). To that end if they need read only access, you can get a participant license, rather than full licenses for those users. If they need to change or edit anything in the repository then they will need to be full users.
You can set these users up as Laserfiche users either at the repository level or in LFDS, which will give them username and password access without the need to link these accounts to active directory.
Hope this helps!
