@kinger37 OK we need to identify some actors here.
128.119.61.55 == pxe booting computer
255.255.255.224 == subnet mask (?? range 192.119.61.33 - 192.119.61.62)
128.119.61.33 == relay agent (maybe a router?)
128.119.61.43 == FOG Server (next-server) boot-file=undionly.kpxe
128.119.10.12 == DHCP server (on another network)
128.119.10.17 == DHCP server (offered by 128.119.61.33 ?)
128.119.101.1 == DNS server
target device is identifying it self to dhcpProxy as IA x86 PC (intel pc in bios mode)
It appears that everything is working. Maybe Sebastian can see something more.
I can tell you the 7040 I have did display the pxe boot screen as I expected. It shows the mac/guid and a spinning cursor waiting for a dhcp response, then ip address and dhcp server, the normal ROM PXE boot screen (something that your display lacked).
I can say that on this system I when into the bios and set everything back to default (bios mode) then rebooted. Then went back into bios and enabled hard drive and network booting only. I think I went and check the network adapter to ensure that pxe booting was enabled and also checked the box to enable pxe booting in UEFI mode. Once I did that and saved the settings, during boot I pressed F12 and selected the bios network boot option.
