      This is strange. This is the second issue we have relating to pxe booting not working for uefi but working for bios.

      What error are you seeing on the target computer when pxe booting in uefi mode?

      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!

          @lebrun78 Well than it doesn’t receive PXE boot information at all. Can you take one of those machines and put it into the other VLAN. Does it PXE boot??? Just want to make sure this is not a model specific issue.

          Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                @lebrun78 Please post output of the two commands: ip a s and ip r s

                      Then you might post the output of the same commands for the DHCP server.

                            @lebrun78 Sorry I was not clear. From the target computer side, how do you know it didn’t work. Did you get a PXE-XXXX error?

                                Do you have an example for a more wordy client ? I use libvirt for virtualisation, but I think it does not support uefi pxe boot.

                                  @lebrun78 ok I think what we will need next is to have you install wireshark on a witness (extra) computer and use the capture filter of udp.port 67 or udp.port 68 Lets see what your dhcp server is telling that target computer to boot in uefi mode.

                                  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!

                                      How could I have a witness ?

                                      Yes I was concerned that the name would not translate good.

                                      What I meant is to have an extra computer plugged into the same subnet as the one that will not pxe boot in uefi mode. On this extra computer load wireshark (free program) and set the capture filter to what I said, so that it only sees the dhcp packets from your dhcp server. This will give us an idea where the problem is. If you save the pcap file (output from wireshark) to an internet file share site, then post the link here I will look at it quickly to see what is the pxe booting client being told.

                                      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!

                                        We are sure the MAC is the one from the UEFI machine not properly PXE booting? Just want to make sure. If it is we do know the DHCP handshake is actually happening.

                                        Looking through the config again I had the idea that maybe naming the classes all the same might be causing the issue. Though this doesn’t explain why only UEFI PXE boot is failing. Still you might want to change the names for one of the groups.

                                        Other than that we’d need to get a packet dump from the DHCP information as suggested by George. You should be able to capture in the command line with a filter: tcpdump -w /tmp/foo.pcap ether host 10:65:30:83:5c:4b

                                        Upload the pcap to a fileshare and post a link here.

                                          Which parameter should I change in the class declaration ?

                                            @lebrun78 Just the names. Make it class "10Legacy" and so on for that subnet.
