That won't work on M1X. The cable modem knows about your NIC's MAC address,
and will not pass packets from other machines on your internal network. Even
worse. If you have 2 systems on a hub, both running a dhcp client, it is
possible that the wrong system will obtain the ip address. This used to
happen occasionally on my thin wire network. It was easy to fix. I am
assuming that the M1X feature that you are referrring to is where the cable
modem is capable of storing more than one MAC address. When a cable modem
boots up, it gets information downloaded from M1X, and is actually assigned
its own ip address. It appears that they limit you to 3 systems connected
through a hub at $14.95/Mo for each of the 2 additional ones. Currently, my
wife and I have 2 separate cable modems, mainly because my system is used
for development and might be unstable. If I were doing it today, I would use
a dedicated firewall to connect to the cable modem. There are some very good
personal firewall systems you can buy for a a few hundred bucks. Or you can
set up a Linux or BSD system yourself. Then you can have as many systems as
you want inside the firewall. Of course there are bandwidth considerations
with a single cable modem approach.
