PXE Server: Control who can PXE boot
So I've created a drbl server for clonezilla, and it's working well the way it is. I'm able to boot via PXE and image perfectly.
However, I'm going to be migrating the server to a larger environment soon. I wanted to know if there was an easy way to control which PC's within my subnet will be able to boot via PXE to my server?
I was guessing that this could rather messily be handled through temp firewall rules?
But I'm looking for a more eloquent solution if it's available.
Any help would be greatly appreciated.
