Code:

17:14:52.804665 IP 192.168.0.2 > 10.2.0.1: ICMP echo request, id 15645, seq 1, length 64 
17:14:52.806881 IP 192.168.0.30 > 192.168.0.2: ICMP echo reply, id 15645, seq 1, length 64 
17:14:52.807016 IP 192.168.0.2 > 192.168.0.30: ICMP host 192.168.0.2 unreachable - admin prohibited, length 92

Well that shows pretty obvious, what's going on:

The icmp echo request goes out to the target
The icmp echo reply comes back from the target
The local host rejects the echo reply and sends itself another icmp message for the failed echo reply

So this points to your client machine, sending the ping, that the paket filter is configured wrongly.

Please show the current rules as requested in my previous post(iptables -L -v- n).

When you execute your ping, and watch the counters with the above given watch command, which rules seem to match for the icmp packages?

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
