Hi Simon,
thanks, it’s working fine for me now. Before releasing 2.76, it would be good
if more people could test this on actual hardware.
Also, there’s one more item that needs to go into the release notes: we now
redirect all clients to port 4011, including the BIOS clients. This is a change
I have included a patch below that makes essentially two modifications to get
PXE working with the UEFI firmware in VMware.
- It only appends the layer number to the file name on BIOS x86.
- It always redirects the client to port 4011. To do that, only the siaddr is
set and neither a boot file

I’ve also been wondering
I’ve posted a patch to make it work:
http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2015q4/010007.html
It works perfectly for a single PXE service. It only uses the PXE menu system
if multiple PXE services are specified as most firmware implementations don’t
fully support it. Make
IOS pxe and all

As it turns out, UEFI does support PXE menus, but the implementations are
rather buggy in that regard. VMware often does not render the menu on the
screen, but you can blindly select the menu entry using the arrow keys and boot
it with the return key. A recent Asus laptop renders the menu, but
if (pxearch == service->CSA &&
match_netid(service->netid, netid, 1))

More wiresharking helped me figure this out. So when UEFI receives a DHCP Offer
or Proxy DHCP Offer with Vendor Class Identifier (option 60) set to PXEClient,
it sends a DHCP Request to the siaddr from the offer, but on port 4011. If the
server then sends a DHCP ACK back to port 4011,
I made some changes to dnsmasq (patch below) that remove the PXE menu system
(the option 43 stuff) if there’s only one menu entry and put the boot file name
and server address directly into the file and siaddr fields. This works fine
for BIOS systems, but doesn’t work for UEFI either.
