If you're using ISC dhcpd, you can try forcing it to send a broadcast response 
using

  always-broadcast on;

in /etc/dhcpd.conf.

The default behaviour of iPXE is to request a broadcast response only if the 
chaddr isn't capable of holding the current link-layer address (i.e. if the 
network interface is IPoIB rather than Ethernet).
