WOL across subnets
I have been using FOG for about three years and love it. Our school has grown to a point that I have had to separate into different ip ranges (192.168.1.xxx and 192.168.50.xxx). The FOG server is in the 192.168.1.xxx range. Machines in the 192.168.1 range will wake on LAN. Another building has computers 192.168.50.xxx these computers will not.
I also use spiceworks to manage my help desk and inventory. It has a WOL feature and it does work in both ip ranges. (I can only wake one machine at a time.)
Any suggestion on what could be causing the Fog to not work.
