Network HELP PLEASE!!

[Andre Cameron <andrec a axxs net>]

Hi,

I can NOT get an internal network setup for the life of me:(  I need some
help please.  Here is my setup:
             |----------------------------|      |------ --------|
             |eth0                    eth1|      |eth0           |
Cable Modem--|dhcp             192.168.0.1|-<----|192.168.0.2    |
             |                            |      |               |
             |       LINUX BOX            |      | WINDOWS BOX   |
             |----------------------------|      |----- ---------|

I followed the linuxdoc.org/HOWTO on IP MASQ'ng  explicitly but when I ran
the rc.firewall I got an error insmod ip_tables.o it said the device or
resource was busy:(

Ok so then I droped the rc.firewall and went into KDE and used the
firewall config tool.  I did not get any errors on boot but it is still
not working.  It now loads the ipchains at boot and I get the [  OK  ] but
my windows box still cant get to the net.  It might be how I have my
policies set.  I have a problem using the KDE firewall config tool because
it is asking me for an IP to forward to from 192.168.0.1 and sence eth0 is
dhcp I can not give it an ip:(  I'm very lost tired and confused and would
REALLY appreciat some help.  This is going on three days and its driving
me crazy.  I am using RH7.1 and would love someone to just shoot me an
email with step by step config instructions, if at all possible;)

Regards,
Andre
