FYI
I solved my problem by doing the following:
1] I then dumped my LinkSys Ethernet card and replaced it with a
3COM905C-TX-M and compiled the driver that is posted on the 3COM site.
2] Changed 192.168.2.X to 192.168.10.X ( I have no idea why but then all the
machines on the internal network could ping one another, if I change them
back then they cannot, got me!)
And that was it. Now my internal network can see one another without any
problems. So it was a combination of the LinkSys tulip driver and the
192.168.2.X addresses.
In the hopes that this might help someone else, enjoy!

Subject: Dual Ethernet Card Problem
Hi list,
I have recently added a second Ethernet card into my Linux box to setup a
firewall between my internal network and our internet ISP. After some hoop
jumping with the tulip driver I have both Ethernet cards and drivers
working. (i.e. either one when configured with the appropriate IP
information can reach the internet) However, my problem arises when I have
the machines on the internal network just try to ping one another. None of
the machines on the internal network can ping any other machine on the
internal network. Here is my configuration.
eth0
IPADDR=24.4.55.108
NETMASK=255.255.255.0
GATEWAY=24.4.55.1
BROADCAST=24.4.55.255
ONBOOT=yes
eth1
IPADDR=192.168.2.1
NETMASK=255.255.255.0
BROADCAST=192.168.2.255
ONBOOT=yes
My test Windows box is using
IP = 192.168.2.2
MASK = 255.255.255.0
GATEWAY = 192.168.2.1
My ISP connection comes in eth0 and I connect my eth1 to the hub. I then
have my other test boxes connected into the hub. None of the boxes can ping
one another.
If I reconfigure so that my ISP connection comes into my HUB and my Linux
box eth0 and other test boxes connect to the hub. And I set my test boxes to
the appropriate IP addresses then all boxes can see the internet; however, I
then cannot setup a firewall.
Any ideas on why none of the machines can ping one another on the local
internal network when configured as above?
Thanks,
Keith Bottner
