External NIC cards not pinging with each other in RHEL 5.1

We have a setup of two nodes which has two NIC cards in each. One is built in and another is D-Link (external NIC card). We are unable to ping to the external NIC cards in both. Eg: Node A has two IPs 192.168.1.10 (eth0) and 192.168.2.10 (eth1) and Node B has two IPs 192.168.1.20 (eth0) and 192.168.2.20 (eth1). These setup has two switches, where 192.168.1.10 and 192.168.1.20 is connected to Switch A, 192.168.2.10 and 192.168.2.20 is connected to Switch B.

The problem here is from 192.168.1.10 is able to ping 192.168.1.20 but not to 192.168.2.20 same with the Node B 192.168.1.20 is able to ping 192.168.1.10 but not 192.168.2.10. when all are placed in same network then all IPs are pinging with each other.

All Linux gurus please help me .. pls treat this request as high prioprity!!

NAME
tgt-setup-lun - creates a target, adds a device to the target and defines initiators that can connect to the target SYNOPSIS
tgt-setup-lun -d device -n target_name [initiator_IP1 initiator_IP2 ...] [-h] DESCRIPTION
Starts tgtd if necessary and creates a target according to the supplied target_name. The format of the target name is as follows: iqn.2001-04.com.<hostname>-<target_name> The target name must be unique. The script then adds the requested device to the target. If specific IP addresses are defined, it adds them to the list of allowed initia- tors for that target. If no IP addresses is defined, it defines that the target accepts any initiator. EXAMPLES
Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81: tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81 and 192.168.10.82: tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 192.168.10.82 Create a target that uses /dev/sdb1 and allows connections from any initiator: tgt-setup-lun -d /dev/sdb1 -n my_target Display help: tgt-setup-lun -h AUTHOR
