IP masquerading, Qwest

Hello:
    I'm trying to set up IP masquerading through my Mandrake 7 box to make my DSL connection available to the rest of the boxes on my
network.  I think I've followed the instructions in the IP masquerading HOW-TO, but it doesn't work yet.  My internal network has addresses
in the ubiquitous 192.168.x.x field.  The Cisco modem that Qwest reports that its address as 10.0.0.1.   DHCP seems to be running fine for
me, and I can access the Web, email,  and news on the Mandrake box.  But the other machines can't see the Cisco modem.
    The masquerading how-to suggests that I try to ping the dynamic IP address from one of the internal machines.  In this case, I know
nothing to try but 10.0.0.1.   It doesn't surprise me that the other machines can't reach the modem at this address.  Is this an inherent
problem with it being assigned one of those "local" IP addresses, or is it more likely that my IP masquerading setup isn't correct?
Should there be some process running to indicate that masquerading is working (such as "dhclient" for DHCP?)
    I looked at the messages file in /var/log, and I only see two suspicious messages:

modprobe:  can't locate module char-major-6 (appears twice consecutively)
last message repeated 2 times (appears six times)

    Could these be indicative of the problem?  If so, what do they mean?  I'm using the "sample" rc.firewall script from the
IP masquerading "howto"; not too secure, I know, but I've got to start somewhere.
    Thanks very much in advance for any help you can give me.
