Linux load balancer ping redirect to other interface

Im configuring centos with load balance with ip route and ip rule

Code:

Eth0 192.168.1.5
Eth1 192.168.5.128
[root@host1 testscripts]# ip route
192.168.5.0/24 dev eth1  scope link  src 192.168.5.128
192.168.1.0/24 dev eth0  proto kernel  scope link  src 192.168.1.5
169.254.0.0/16 dev eth1  scope link 
[root@host1 testscripts]# ip route show table wan2
default via 192.168.5.2 dev eth1  src 192.168.5.128
[root@host1 testscripts]# ip route show table wan1
default via 192.168.1.1 dev eth0  src 192.168.1.5
[root@host1 testscripts]# ip rule show
0:      from all lookup 255
32762:  from 192.168.5.128 lookup wan2
32763:  from all to 192.168.1.5 lookup wan1
32765:  from 192.168.1.5 lookup wan1
32766:  from all lookup main
32767:  from all lookup default

But the problem here when I use

Code:

tgt-setup-lun(8)					      System Manager's Manual						  tgt-setup-lun(8)

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
