I have finaly found out what went wrong !
I don’t know if there is lot of people using Lancom router but here is the solution :
On Lancom’s router, there is settings for PXE server’s declaration. So no need to set the options 66 & 67.
Just go onto “IPv4” menu then “BOOTP”. Clic on “Boot images…” button and add your FOG server by typing his IP address et boot file (undionly.kpxe). (example on the attached file)
After that, you have to add the station and associate it with your FOG server.
In the same menu as above, clic on “Stations…” and add your computer by typing his MAC address, IP address, station name and PXE server previously declared.
Thank you again for your help and your time 🙂
