Follow-up Comment #1, bug #55636 (project grub):
Hi, I just faced with the same issue when implementing GRUB support for LTSP
(https://github.com/ltsp/ltsp/pull/108#issuecomment-567744162)
I was thinking that problem can be simple solved my setting correct
next-server (SIADDR) option on proxy-dhcp server, but I was wrong because grub
drops into rescue shell any way:
iPXE (PCI 00:03.0) starting execution...ok
iPXE initialising devices...ok
iPXE 1.0.0+ (0600d) -- Open Source Network Boot Firmware -- http://ipxe.org
Features: DNS HTTP iSCSI TFTP AoE ELF MBOOT PXE bzImage Menu PXEXT
netO: 02:00:10:ad:4a:47 using virtio-net on 9000:00:03.0 (open)
[Link:up, TX:0 TXE:0 RX:0 RXE:0]
Configuring (netO 02:00:10:ad:4a:47)... ok
netO: 192.168.67.267/255.255.255.0 gw 192.168.67.1
Booting from PXE menu
PXE
PXEBS (netO type 640)... ok
Next server: 192.168.67.10
Filename: Iltsp/grub/i386-pc/core .0
tftp://192.168.67.10/ltsp/grub/i386-pce/core.9... ok
core.0 : 47787 bytes [PXE-NBP]
error: time out opening ‘/ltsp/grub/i386-pc/normal.mod’ .
Entering rescue mode...
grub rescue>
If I call set I will see main dhcp server address only:
grub rescue> set

net_default_interface=pxe

grub rescue>
A little investigation shows that proxy-dhcp sending correct next-server
(SIADDR) option in it's replies:
