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?

vde_tunctl

VDE_TUNCTL(8)						      System Manager's Manual						     VDE_TUNCTL(8)

NAME

       vde_tunctl -- create and manage persistent TUN/TAP interfaces

SYNOPSIS

       vde_tunctl [-f tun-clone-device]  [-u owner]  [-t device-name]

       vde_tunctl [-f tun-clone-device] -d device-name

DESCRIPTION

       vde_tunctl  allows the host sysadmin to preconfigure a TUN/TAP device for use by a particular user.  That user may open and use the device,
       but may not change any aspects of the host side of the interface.

       vde_tunctl is a simple copy of tunctl done for practical purposes.

USAGE

       To create an interface for use by a particular user, invoke tunctl without the -d option:

       # vde_tunctl -u someuser
       Set 'tap0' persistent and owned by uid 500

       Then, configure the interface as normal:

       # ifconfig tap0 192.168.0.254 up
       # route add -host 192.168.0.253 dev tap0
       # bash -c 'echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp'
       # arp -Ds 192.168.0.253 eth0 pub

       To delete the interface, use the -d option:

       # vde_tunctl -d tap0
       Set 'tap0' nonpersistent
