routing problem? 2 hosts thru dialup server with Crossover Cables/No Hub



Good morning,

i am trying to establish a network using

1 RH-9 server  [ LAN ]
2 hosts [ NK and LK  ]

The dialup server [ LAN ] has 2 nics [eth0 and eth1]
which are connected to [NK] and [LK] by Crossover Cables directly
[I'm not using a Hub]

My Problem:

I can ping successfully from LAN to both LK AND NK...

I can ping from NK to both of the nics on LAN, but not to the nic on LK.
And i can access the Internet from NK as well.

I can not ping anything from LK to LAN or NK

Is my routing screwed up?  I'm confused.
Thanks in advance for any help I'm given.

Johnny


My routing setup.....
[root lan root]# netstat -nr
