FC 4 Networking bridge

[Mark]

Hi all

Perhaps I am being a lil dim here as a new linux sysadmin personage 
(previous preference was for windows, emphasis on "was")

For some reason I have not been able to get a working network along the 
following lines.

NOTE this network is purely for systems testing, bandwidth etc, hence 
the daisy chain effect.

I have 2 servers, both running FC4 and a cisco router.

The aim is to test throughput from one server to the other via the cisco.

My proposed solution is as follows:
Both servers have 2 gigE nics
Cisco has 2 interfaces which I have named ciscoLan and ciscoWan

Basically I want server 1 with eth0 connected to my DMZ network (and the 
world at large) witha  public IP address
I then want to configure eth1 with another public IP to connect directly 
to the ciscoWan

I already have the cisco connected via ciscoLan to server 2 using NAT 
and private IPs but I cannot get eth1 on server 1 to come up with the IP 
address I need and then talk to the cisco.

I think the issue may be that I need to enable bridging of sorts between 
the 2 NICs, as MS does with ICS etc.

So the question is, how do I acheive that?

As far as I can tell, I have all the interfaces configured correctly.

I can`t give the actual IPs here, but I will give an example:
All Xs give the same subnet

Server 1
/etc/sysconfig/network
NETWORKING=yes
HOSTNAME=test-server-01.domain.net
GATEWAY=X.X.X.33

/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:14:22:22:04:1A
ONBOOT=yes
TYPE=Ethernet
IPADDR=X.X.X.41
NETMASK=255.255.255.224
GATEWAY=X.X.X.33

/etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
HWADDR=00:14:22:22:04:1A
ONBOOT=yes
TYPE=Ethernet
NETMASK=255.255.255.224
IPADDR=X.X.X.42
GATEWAY=217.30.126.33  <- is this a problem????

Have I really missed something and thats why this server can`t talk to 
my cisco on eth1?  By the way, the cisco has an IP of X.X.X.62

I am trying to have both eth0 and eth1 having IPs only 1 apart and the 
gateway for eth1 is set to the same as eth0.  Is this adding to the 
problems?

I can solve it fairly easily by installing windows on server 1 and 
configure ICS etc, but I would rather avoid that for 2 reasons:
- having FC4 on the server is beneficial for us after this roject
- I don`t want to give in to this problem, I would rather solve it.

Thanks in advnace.
