I have just discovered that somehow all the MACs are changing sometime after the final successful DHCP lease.
My DHCP server is set to only answer to specific MACs, so if I add in the “new” one, it works.
No idea how this is happening, I’ve never seen MACs just suddenly change like this.
It sucks that now I have another MAC per server to deal with, but at least it’s working.

I’m trying to get a Dell R360 registered with FOG.
iPXE boot works fine, it does about 3 DHCP requests which all succeed. After the last one it appears to try another DHCP request and then an HTTP request to the FOG server (10.2.79.12) which fails.

The odd thing is I can boot the server to an ISO, it gets the exact same DHCP lease, and I can curl the URL just fine.

Is there a way I can get more verbose output from the period where it is failing?
