there are many types of NAT and these type can work simultaneous AND some not work
NAT 1:1 using One IP outside interface can not work with dynamic NAT using same interface <<- this I think your case
PAT 1:1 using port NATing to one IP outside interface can work with dynamic NAT using same interface
solution I think
ip nat inside source static icmp <ip><ip>
ip nat inside source list 1 interface <x> overload

Hello
If your static nat is not working, did you ammed the NAT ACL ( as I suggested) to deny that host from being dynamically translated?

Me when I use static NAT I remove all configurations that are related with dynamic NAT.
