I believe you have to route those IP addresses. Since you got the
enhanced, you probably got the external Alcatel. That device is a
bridge. It has no address, but will "bridge" the data to your ethernet
card which does have an address. I don't think you can plug the wire
into a switch, because the packets won't know where to go. The router on
Pacbell's side has no knowledge of you NIC cards MAC addresses that are
also plugged into the switch. So, you will have to plug the wire into
your Linux box into a NIC directly from the Alcatel. From there you have
several options. You can put multiple NICs in the machine. That machine
will be your gateway. You then can assign another NIC in that gateway
an IP address. That takes two of your IP's. Then you can run that wire
to your switch and you can have three other machines on that subnet
with the routable IPs. That's just one of your options. Other options
would be to Masquerade, or to alias all those IP's to the NIC that runs
between your box and the alcatel. Then you could forward traffic that
hits the routable NIC back into one of your boxes with a private IP.

yes
