SOLVED PXE boot fails due to incorrect server IP

[willjasen]

I’m setting up a FOG server and having trouble getting the PXE boot working. I’m pushing out the correct DHCP options via the router:

Option 66: 10.10.10.10
Option 67: undionly.kpxe

However, the boot fails. I performed a packet capture on the port where the client is connected and interestingly, the client receives the correct DHCP options but is trying to download from the default gateway at 10.10.10.1 instead of 10.10.10.10

Any ideas?

I figured it out!

I’m using Meraki as the router and setting option 66 and 67 doesn’t work (well… 67 does but 66 isn’t enough)

Under DHCP, the appropriate boot options need to be set.
