Hi Gents,
I am no expert, but hopefully my input can help a little.
First, quick MACLookUp on the MAC in the screenshot 080027 cadmus computer systems, looking for cadmus computer systems, VirtualBox came up. so that’s that. https://www.virtualbox.org/pipermail/vbox-dev/2011-August/010036.html
Just this past week i had an issue with our POS system that runs over PXE (Nothing to do with FOG).
Scenario
EXSi 5.5 Upt 2 host running Windows 7 guest and inside the guest VirtualBox. Inside VirtualBox a Virtual machine running our POS system (Point of Sale jst fyi 🙂 ) that is called via PXE.
The PXE call would time out, which i think is the problem you are having.
The way i was able to make it work was by ENABLING – PROMISCUOUS MODE – in the EXSi Host.
In Virtual box not sure how to enable, but a quick search tells me that all you have to do is change the NIC you are using the FOG with to Bridged Adapter instead of Internal Network which is most likely what you are using.

Just to try change your FOG server network adapter to Bridged Adapter (Literally will simulate you physical NIC ) to see what happens, it wont hurt !!!
Again way far from expert, but in my case using fog, since this beautiful software uses PXE and DHCP among a lot more things. I though to myself, just to be on the safe side i will keep my FOG server completely isolated from my actual network, because in my case i just use it to clone computers and more important i already have a DHCP and PXE service already running … that would be a call for problems to put my fog server on the same network !!!
Hope this helps a little, if not well i shared something !!!
Cheers mate !!!
