      @Pikmin We find depending on your network setup (if your real dhcp server sends out some of the boot information) the pxe-service fields are needed.

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

        @Pikmin I just looked at my dev box and I still had this structure in the ltsp.conf file.

        dhcp-match=set:e6230,97,00:44:45:4c:4c:38:00:10:36:80:4e:c4:c0:4f:4a:58:31

dhcp-vendorclass=UEFI,PXEClient:Arch:00007

dhcp-boot=tag:UEFI,tag:e6230, snp.efi, 192.168.112.24, 192.168.112.24

        With no pxe-service lines. Note for the dhcp-boot line I had to use tag: to identify both tags and to create the and condition.

        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

          It would be interesting to know how well this one works.

            I’ve tried that but didn’t work for me, it gets to the boot menu but doesn’t seem to know what to boot, so the menu counts down and nothing happens
            EDIT:
            Last message I get is
            PXE-E21: Remote boot cancelled?

            This is what I get in the log

              Please explain, are you getting to the FOG iPXE boot menu?

                Also looking at your log file snp.efi is being sent. If you used my config file it should have sent intel.efi (right not I’m not saying its right or wrong kernel for that system I’m just looking for the same as I told it).

                  Ah ok then your dhcp server is sending out info too and the client is getting confused. Do you have time to debug this so we can see exactly what’s going on?

                  You will need the pxe-service commands but lets understand what’s going on first.

                    The Windows DHCP Server is set to PXE Boot SCCM

                    Also note that without using the netmask in the range directive PXE boot doesn’t work
                    dhcp-range=192.168.131.149,proxy,255.255.0.0

                    I also have ip helper on the switch so I can netboot from other vlans

                      @george1421 Using the configuration file that created the PXE error 21.

                      Lets grab a pcap of the pxe booting process. This works the best if the FOG server and the target computers are on the same subnet. https://forums.fogproject.org/topic/9673/when-dhcp-pxe-booting-process-goes-bad-and-you-have-no-clue

                      Since you have an IP helper, your fog server may not be on the same subnet. It would be ideal if they were on the same subnet since the filter we will use looks for dhcp, proxydhcp, and tftp communications. If this can’t happen then use wireshark on a computer plugged into the same subnet as the target computer.

                      Understand this is part helping you and part adding to the collective knowledge of the forums. It would also be nice to know what your dhcp server is for background info.

                          This raises a question if the dnsmasq server is on the same subnet as the pxe booting client computers. If not did you add the dnsmasq server as the last dhcp server in your dhcp helper list? dnsmasq will not supply any dhcp addresses it just needs to be made aware that a dhcp request was places so it can reply with its proxydhcp answer.

                            Great, so now we know the “match” part is working. We just need to get the target computer to believe the proxydhcp response.

                              Note this one will NOT boot your computer. I’m interested in what was matched. Some is an educated guess so lets see what is matched.
