Can somebody tell me if something with my NAT isn't working correctly?!

In the attechments you find my whole Network in PacketTracer. Can somebody tell me, if my NAT is working correctly?

It should be very simple, as it is simply about 5 lines of code. The dynamic NAT is working on the R7-Router.

 

Here the running-config of R7:

 

R7(config-router)#do show run

Ok,I have one last question: At the moment I am not able to ping from one IPv6-PC to another IPv6-PC. The packet dies in simulation mode instantly at the PC and does not go further. Does anyone have any suggestion why that is the case and how I can get the PING problem solved?

And just a short question in addition: In the lower part of my topology you see my IPv6-Static-Routing implementation. I just wanna know, is it difficult to get a transition from IPv6 to IPv4, so that everybody in the network can communicate to each other?
