Shalom,

Check the network configuration.

Set the gateway for each NIC card in /etc/sysconfig/network-scripts/ifcfg-ethX not in /etc/sysconfig/network

If the gateway is correct, you should function properly on both networks afterthis change.

> its correct only

If everything were correct, then things might
work properly. If things aren't working
properly, then perhaps not everything is
correct.

So far, only _you_ can see any of the useful
information.

What are the IP addresses?

What are the routes?

Showing actual commands with their actual
output is usually more helpful than vague
descriptions and interpretations. Don't
_tell_ us that things are correct. _Show_
us what's true.

Hi Steven

My ipaddress is 10.0.4.3
subnet mask is 255.255.255.0
Default gateway 10.0.4.1

Oneside router ip is 10.0.4.1
another side router ip is 40.40.40.2
for both subnet mask is 255.255.255.0

Another server ip is 10.0.4.2

same subnet mask & default getway.

The thing is from 10.0.4.3 server is not pinging 40.40.40.2 but 10.0.4.2 is pinging

Now tell me where is the wrong from my side?

fighting is not the solution
