I do use them by redirecting traffic from the linux box to the destination boxes (such as all trafic for public IP 2 goes to 192.168.21.2, for example). This works fine, *except* in this particular case, where any NATing is not an option. I need the computer behind the linux box to actually own the public address, because it signs packets with it.
