Port forwarding, dmz , 3 network cards and a quake3 server -=- Long-=-

help!

I am running ClarkConnect 2.0 based on rhat 9.0. In this box I have 3
network cards.

I am running SuSE 8.2 in the second box running as a quake3 server.

Here is my ifconfig output from the ClarkConnect box:

eth0 is connected to my cable modem and uses dhcp client to get its ip
address from charter.net

eth1 is my 2nd card that connects to a 24 port switch to let the
internal network connect to the internet.

eth2 is my 3rd network card that is supposed to connect to my quake3
server box.

here is the output of route -e -n -v

I have tried several ways to get the 3rd nic to talk to the one and
only nic in my quake3 server. here is the ifconfig output from the
quake3 server:

Here is the output of route -e -n -v on quake3 server:

As you can see the gateway on the quake3 server is the same gateway I
use for all my computers: 192.168.1.1

Now, I have also set up port forwarding on the ClarkConnect box, here is
the output: ( yes I probably have way too many entries for the port
forwarding, but I added all the possible ways I could think of to route
my quake3 server through the ClarkConnect box).

<------------------------------------begining - port

<-----------------------------------------end - port
forward----------------------------------------------->

Now, I have tried a few things...

1. I tried to use a patch cable.. (at least that is what the package
said it was) and a cross-over cable..
to connect the 3rd network card in the ClarkConnect box to the primary
network card on the quake3 server. They would not ping each other, or
the network. (from the quake3 server).

2. I tried to use 2 known good cables from 2 brand new linksys ethernet
cards, To connect the 3rd network card in the ClarkConnect box to a
switch all by itself and the primary network card in the quake3 server
box to the same switch. They still would not talk to each other, ping
each other, or give a network connection to the quake3 box.

3. If I plug the network card in the quake3 server box into the 24 port
network switch, it talks to the internal network and to the outside world.

4. The ClarkConnect box is setup to see 3 network cards as seen in the
/etc/modules.conf

<------------------------------------------begining -
/etc/modules.conf----------------------------------->
cat /etc/modules.conf
alias eth0 ne2k-pci
alias eth1 tulip
alias eth2 tulip

<-----------------------------------------end -
/etc/modules.conf------------------------------------>


I want to set this box (quake3 server) up to be on the dmz with port
forwarding to the outside world, so my quake3 server shows up in online
quake3 server lists. (This is so the [CLlug] clan can get stats, which
are posted on numerous stat pages on the internet). And, so when I host
a Lan party next Saturday, other cllug.org members can log on and play
with us too, esp. those that cant make it..

I tried to set the quake3 server box up to get it's ip address via dhcp,
but for some reason the ClarkConnect box is not handing out dhcp addresses.

<-------------------------------------------begining - ps -aux | grep
dhcpd--------------------------------->

[root@firewall etc]# ps -aux | grep dhcpd
root 2356 0.0 0.0 2272 76 ? S 12:16 0:00

<---------------------------------------------end - ps -aux | grep
dhcpd-------------------------------->

Could someone please help me!?

All the network cards in all the computers are brand new, and work fine.

I could probably change out the 3rd network card in the ClarkConnect box
for another new one, just for poops and giggles.. but I dont think that
will solve the problem, I.E. lights on network card come on.. rhat's
hardware detection program found the new network card on first boot,
after installation of said new network card.

The quake3 server box has used, SuSE 8.2, Slackware 9.1, FBSD 5.1 and
FBSD 4.8, nothing fixes the problem.

Please help.

further info can be given on request.

Thank you
