Right.  So... You watch the PXE requests to determine what UUID PXE config file (or MAC based PXE config file) is being requested.

Then construct a file similar to the stock file you use for all the other systems, labeled to match the request. BUT the image/FreeBSD configs IT provides instruct the booted 
system to use the interfaces that match your requirements.

I haven't done a FreeBSD PXE config in a long while, so I have to leave the exact details of that to you, but that's where the magic happens.
