strange network problem

system config. Red hat ES 5 . multiple network cards. front end and back end networks.

Problem:
Here is what I have diagnosed on linux 6 .....other machines on the network if you try to get there do not see linux 6, a ping results in “no route to host” message. However the system is running fine. I ran a ping from linux 6 outbound to linux 1 and it never lost a packet (84000) of them, but from linux 4 I could not get to linux 6. As soon as I pinged linux 4 from linux 6, all of a sudden linux 6 saw the machine and pings went through. So outbound from linux 6 there is no issue. I have never seen this in the 25 plus years I have been doing this, and I will continue to work on it to resolve the problem.

If anyone has any idea how to figure this one out I am open to suggestions.

Please provide the details for each server, ifconfig -a, route, arp -a.

Thanks.
