I have essentially the same problem, and have spent considerable
time trying to get it to work with no success.

I have a cable modem connected to my Red Hat 7 box on eth0, and eth1
connecting to a 5 port hub which I'd like to setup on the 192.168
private ip's and do masqerading for.  Here's my applicable files:

[ifcfg-eth0]

DEVICE="eth0"
BOOTPROTO="none"
BROADCAST=24.14.246.127
IPADDR="24.14.246.95"
NETMASK="255.255.255.128"
NETWORK=24.14.246.0
ONBOOT="yes"
IPXNETNUM_802_2=""
IPXPRIMARY_802_2="no"
IPXACTIVE_802_2="no"
IPXNETNUM_802_3=""
IPXPRIMARY_802_3="no"
IPXACTIVE_802_3="no"
IPXNETNUM_ETHERII=""
IPXPRIMARY_ETHERII="no"
IPXACTIVE_ETHERII="no"
IPXNETNUM_SNAP=""
IPXPRIMARY_SNAP="no"
IPXACTIVE_SNAP="no"

[ifcfg-eth1]

DEVICE="eth1"
ONBOOT="yes"
BOOTPROTO="none"
IPADDR="192.168.1.1"
NETMASK="255.255.255.0"
NETWORK="192.168.1.0"

I do have masqerading rules running for the ipchains setup I'm
running.  I've setup the 2 client machines as 192.168.1.101 and
192.168.1.102, and have both pointing to eth1(192.168.1.1) as their
gateway, and my cable providers DNS servers.  Can anyone tell me
what my flaw is?  The 2 machines have no luck talking to the
internet connected this way.  Are there some route commands needed
here or something?  I do show lots of errors on eth1 on an ifconfig:

eth0      Link encap:Ethernet  HWaddr 00:50:BA:04:73:79  
          inet addr:24.14.246.95  Bcast:24.14.246.127  Mask:255.255.255.128

          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16128  Metric:1
          RX packets:1721 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1721 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 

Any and all help is greatly appreciated!!

TIA,
