i started bochs virtual machine with emulated ne2k ethernet this way

ne2k: ioaddr=0x240, irq=9, mac=b0:c4:20:00:00:00, ethmod=fbsd, ethdev=fxp1


it works but...

i can see bochs virtual machine from all machines in network to which fxp1
is connected except.... machine running bochs.

am i doing something wrong?
