Policy based nat - can't get it right...

Question

Hi out there
I need to implement some policy based nat to hide a DMZ network on a site - to avoid routing problems. This should also be faily simple by defining a route-map and then looping the traffic around a loopback-interface which is defined as outside nat.
I define the LAN interface as inside - assign the route-map policy to it and loop the traffic around the loopback interface to get it nat'ed.
this also works - to some extend. The traffic is correctly natted and the traffic send out of the wan interface ( f0/1) - the remote site replies and sends the traffic back - and when it then enters my R2 router - it is dropped ????
I have ran out of ideas - please try to take a look - here is the config of R2 (I issue my test from R1 which is 80.0.0.1 and has a source-interface for 192.168.10.1)
Config of R2:
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
hostname R2
ip cef
no ip domain lookup
ip domain name lab.local
ip auth-proxy max-nodata-conns 3
ip admission max-nodata-conns 3

ip nat outside
ip virtual-reassembly

ip address 80.0.0.2 255.255.255.0
ip nat inside

ip address 81.0.0.2 255.255.255.0

ip forward-protocol nd
ip route 192.168.10.0 255.255.255.0 80.0.0.1
no ip http server

ip nat inside source list 1 interface Loopback2 overload
access-list 1 permit 192.168.10.0 0.0.0.255
route-map To_loop2 permit 10
match ip address 1
set interface Loopback2

the easiest way is constructing your menu with frame labels
now i have no way of knowing how you are constructing it ..so
this may not work for you ...i assume that you have created a main
button ...that has been converted into a symbol & then
duplicated to create all other buttons
okay here it goes ..i hope i dont confuse you
i will explain how to create 1 button with 4 submenu items
with the trems that i mentioned above
but iam not going to explain all the details of creating a
whole nav bar
because it just takes too much typing ...i assume you already
know this
sooo ! ...lets say this is the Portfoio button ...inside the
symbol now
create 8 layers ...the order is going from top to bottom
actions
labels
submenu Logos
submenu Illustration
submenu Animation
submenu Coolstuff ."you will name your button items how you
like" ...
main button....lets just say Portfolio !
invisible btn for main button
so now on with the hard stuff
create 20 frames ...stop action on frame 1 ...frame 9
...frame 20
on the labels layer now ....name frame1 "Closed" ...frame 10
"Open"
on the submenu Logos layer ...create a keyframe on frame 10
all frames before the 10th frame will be blank frames
repeat that for the rest of the submenu items
on the main button layer you will just place the main
Portfolio button on frame 1
& on the invisible button layer ..the inv btn is going to
be placed on frame 10
all this is iam hoping your have converted everything into1
symbol
all you need to do know is attach code to the main Portfolio
button & the invisible button
so click on the Portfolio button
on (rollOver) {
gotoAndStop("open");
invisible button
on (rollOver){
gotoAndPlay("closed");
& that should be good ...very simple !
then just repeat this process for every button that makes up
your nav bar ....& it doesn't matter if your inv buttons
overlap each other or your main nav buttons are touching each other
