[Bug 1604496] [NEW] TFTP boot: error: time out opening '/grub/i386-pc/normal.mod'

[Robster]

Public bug reported:

My DHCP server sends the PXE commands, grub gets load from the TFTP
server, but it is unable to load the grub.cfg file since it is trying to
TFTP to my firewall instead of the TFTP server.

1. DHCP and PXE server are NOT on the same subnet 
2. Grub time out when it TFTP cause it is trying to TFTP to an invalid server (It tries to TFTP to the firewalll) 


the website below have a fix for the problem but it is not implemented in the latest Ubuntu grub release
