I'm a wee bit confused here, but I do understand what you are trying to
First, did you compile a new kernel with the following option?:
Second, try giving both PC's a static IP address, and disconnect the
FBSD box entirely from the network (so you essentially have a 2 pc
network), then commence testing.
