IP NAT questions

seeking guidance.  I have an ISR4331 version 17.3.5 and working to configure NAT and having difficulty.  Consider the g0/0/0 interface the inside and G0/0/1 the outside.   TCP traffic initiates from the outside.  Source /24 network will target an IP address that will be NAT'd to an inside global (as the destination address).  Traffic from the outside network is to be translated to a secondary IP on the inside interface.  The following are the NAT statements used in the configuration - 

 

ip nat inside source static 10.240.1.11 172.16.30.67
ip nat inside source static 10.240.1.12 172.16.31.149
ip nat outside source static network 172.31.240.0 192.168.100.165 /32

Hello.

 

I wanted to inform that I tried your suggestion but still, the ip nat outside source route-map map-aws pool pool-aws was not performing as needed and have decided to perform this "hide NAT" function at our firewall, which is the next hop router from this isr4k.  The project was more urgent than putting more time into it. 

 

I do appreciate your time spent.

I will do simply Lab and send to you in case in feature you will use it.
