  Well... ;-)

Since I am fiddeling around with it for hours now I recently found a 
better solution than NAT:

Bring up a virtual interface and set the host as gateway. ip_forward has 
to be enabled on host

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
#up ip addr add 10.10.10.10 dev eth0

iface eth0:1 inet static
     address 10.10.10.10
     netmask 255.255.255.255
     gateway 192.168.2.101 #The Host's IP


Its a bit of a strange setup but it works stable. - And for the client 
it looks pretty clean :)
