Oracle RAC - Cannot Ping from RAC1 to RAC2

Hi all,

I've created two VMs (RAC1 and RAC2) on VMware Server2 for Oracle 10g RAC.

Each VM has 2 network adapters:

eth0: public

eth1: private

But, Into RAC1, when I try a ping to RAC2, I got the error destination host unreachable.

The subnet and the net mask is OK, I've set the /etc/hosts.

From my Host PC, I cannot to perform ping to RAC1 and RAC2 too.

I've tryed to set the ethernet to hostonly and bridged, but I got the same problem.

Is there any configuration we need to do?

thank you very much!!!!
