Hi! I was thinking, is there a way to use a linux box with Samba running in the DMZ of a firewall and to validate logons from the internal network? I.e. the users workstations are on the protected net on 192.168.111.xx and the Samba PDC resides in the DMZ, running subnet 192.168.222.xx. If it's possible, what ports need to be open?
