default gateway problem.

["Kumar" <vramnarayan@triniti.com>]

Hi , 

Have installed RedHat 7.2 ( kernel -2.4.7-10) with two nic's. One is having an internal IP and the other a public IP. 
There are no Ipchains/ IPtables rules nor there are any nating rules. 
Have enabled IP forwarding.  The default gateway of the internal IP is the public ip, right ? 

When some other machine is connected to the network giving the same ip, there is no problem. 
But when I do ping -b <broadcast address >  I get response from some of the host which are on the public ip on the same subnet. 
Have also edited the hosts file with the machine specification and have also edited the nsswitch.conf for files, dns. 
Have also checked for the broadcast address and the subnet mask displayed in the ifconfig command and everything seems to be ok. 
I have tried looking for irq conflicts in the logs, but didnt fine any. And assuming it has any irq conflicts then in that case the card should not 
function at all right ??

I am facing the following problems : 
a) The machine is not able to connect to the default gateway, but it can connect to other machines on the same subnet. 
      So it is not ale to connect to the internet, since it canot connect to the gateway. 
b) comand like route, netstat takes exceptionally long time to display the output.
     I know we can always do route -n to disable the dns lookup, bu in the other linux boxes it does nto take his much time.  

I had tried some commands before rebooting the mahine in iptables.Have rebooted the machine n number of times for various reasons after that. 
I have checked the rules by : iptables -L and iptables -t nat -L commands. 
Is there any other command to check if there are any rules , or any oher typ of firewll settings ??? 

What could be the problem ?

 Please help.

Thank you for your response and help in advance 
Warm regards, 
Kumar.
