zywall 70 NAT problem

Hi,
I have a Zywall 70 and i need to make a 1-1 NAT and one M-1 nat as in
the example below....
For doing so, i need to enable the full feature nat option.
I try to do it, but if I enable it, the access to the 192.168.0.4,
from the WAN, don't function succesfully..
Then I tried to move the the 1-1 NAT in the first place, but I'm not
able to move it in the top of rules....
Have you got any suggestion?!
Thanks
