PCBSD 7 : Network Install via USB BootOnly

[kmf]

Hi there,
I'm trying to install PC-BSD over a network,
I'm booting via a USB stick,
I created a Webserver that hosts the files, that I copied out of the image into the DcoumentRoot,
and when I choose "Install from Network",
I choose DHCP, get a lease,
but when I enter my path it fails, when I choose Internet install, it works,
so I know the connection is working,
I have also recreated the layout of the files on the FTP server, when I launch a "xterm" ... I can manually fetch the file, and it works.

example : "fetch http://192.168.2.1/netinstall/PCBSD.tar.lzma"

Any Ideas ?
