Dear Andrew,
Thank you for the hints. I tried removing option 60, but without success. I
also changed the setup from PXE discovery control to a PXE menu based control,
but also without success. During the testing there was once a DHCP request from
the boot client, but the subsequent DHCP ACK was also ignored.
In the meantime I tested the PXE boot using a Sony Vaio notebook with PXE 2.1
and the boot configuration below and it succeeded.
Any more ideas?
Best regards
Thomas

Betreff: Re: [gPXE] Intel Undi PXE 2.1 Client Ignores DHCP Offer Messages with
gPXE Filename from ISC DHCP Server
Hello Thomas,
DHCP option 60 (when set to "PXEClient") is an instruction to a PXE client that
the DHCP offer it just received doesn't contain what it is looking for, and
that the PXE client should instead contact the same DHCP server, only on port
4011 to get the information it needs, such as a filename and TFTP server, in
order to continue the PXE boot process. This facilitates housing a PXE boot
server and DHCP server on the same machine, as, since a PXE boot server is an
implementation of DHCP itself, they both use port 67 by default.
In your case, your DHCP server /is/ your PXE boot server, so you don't actually
want to specify that option at all. The name of DHCP option 60 itself is
rather confusing, and its purpose also rather vague, unfortunately :(
*Eyeballing your Wireshark dumps a little more closely* ...that does appear to
be the problem. Give a try at removing option 60, and it should work as you
expect (apologies if I missed something).
Cheers,
Andrew Bobulsky
