Thanks. > There have been no changes to this code since 2.71, so upgrading won't save you. I have no idea if this has ever worked. I've certainly never tested it, and it wouldn't surprise me if no-one has made it work: it's pretty niche. I don't, AFAIK, have any suitable hardware to test this, but you may be in a perfect position to do what I'd do next, which is to compare the PXE packet that WDS sends, and which works, with the one the dnsmasq sends, and is ignored. On a good day, that will give us one, obvious, difference and an easy fix :-) Could you post complete packet captures suitable for loading into Wireshark, or send them directly to me if you prefer?
