@lmoysidis I’m not using fortigate but check out the following article: https://docs.fogproject.org/en/latest/installation/network-setup/proxy-dhcp/?h=
I needed to dynamically assign a boot file based on vendor class and dnsmasq did the trick!

Ok so the system in question has an on board nic (enp128s31f6), 1 single port Intel PCI-E Gigabit NIC (enp5s0), and 1 dual port Intel PCI-E Gigabit NIC (enp3s0 and enp4s0).

So I booted the system with a Linux system rescue USB key. The network cable is plugged into the single port nic. You can see that it has the IP address 172.16.57.22 was fetched. Without any issues. The mac addresses on the identified nics are:

enp128s31f6 - d4:a2:cd:b7:17:f2 enp3s0 - 00:13:3b:50:b2:b0 enp4s0 - 00:13:3b:50:b2:b1 enp5s0 - ec:08:6b:04:f9:d9 (the one that is attached to the network cable)

Now when I boot the system up into debug mode with FOG into the FOS environment it seems whatever port is pluged into the lan it adopts another NIC’s mac address as shown below:

Now you can see when the fog client boots the mac address changes on the port that is connected to the LAN as:

enp128s31f6 - d4:a2:cd:b7:17:f2 enp3s0 - 00:13:3b:50:b2:b0 enp4s0 - 00:13:3b:50:b2:b1 enp5s0 - ec:08:6b:04:f9:d9 --> Changed to 00:13:3b:50:b2:b0 (the one that is attached to the network cable)

Now I’ve plugged the cable into enp128s31f6 and setup dhcp on that port as well and tested it. When the fog client starts all of sudden the enp128s31f6 has another NIC’s mac address…

Just a re-cap if I pull the two network cards, and do the re-image on the system I have no issues. It only occurs when I put an additional nic into the system… Any suggestions?
