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?

aggregate-ios

AGGREGATE-IOS(1)					      General Commands Manual						  AGGREGATE-IOS(1)

NAME

       aggregate-ios - optimise a concatenated set of cisco/IOS prefix filters to help make them nice and short.

SYNOPSIS

       aggregate-ios <source_config >optimised_config

DESCRIPTION

       Takes  cisco IOS configuration on stdin, and optimises any prefix filters found using aggregate(1).  Optimised filters are produced on std-
       out.

OPTIONS

       None.

DIAGNOSTICS

       Any diagnostics produced by aggregate(1) are passed through on stderr.

EXAMPLES

       The following configuration fragment:

	 ip prefix-list AS65530 description Foo, Inc
	 ip prefix-list AS65530 permit 10.1.0.0/16
	 ip prefix-list AS65530 permit 10.2.0.0/16
	 ip prefix-list AS65530 permit 10.2.1.0/24
	 ip prefix-list AS65530 permit 10.3.0.0/16
	 ip prefix-list AS65531 description Bar.Com
	 ip prefix-list AS65531 seq 5 permit 192.168.1.0/24
	 ip prefix-list AS65531 seq 10 permit 192.168.2.0/24
	 ip prefix-list AS65531 seq 15 permit 192.168.0.0/19

       is optimised as follows:

	 ip prefix-list AS65530 permit 10.1.0.0/16 le 24
	 ip prefix-list AS65530 permit 10.2.0.0/15 le 24
	 ip prefix-list AS65531 permit 192.168.0.0/19 le 24
