NAT outside many to 1

[NetworkZero]

I have a scenario where I need to NAT a 10.0.0.0 /24 network coming into my routers tunnel 1 interface to a single IP and have yet been successful in doing so unless I do nat overload and define the tunnel 1 interface as ip nat inside and then my gi 0/0/0 as ip nat outside, basically reversing how it is normally done.

I have a site to site IPSec VPN on my router, interface tunnel 1.  The remote end has a private network of 10.0.0.0 /24 that needs to come inbound on tunnel 1 and into my network.  The problem is 10.0.0.0 /24 overlaps with existing networks so I need to NAT it to preferably a single IP, the IP of interface gi 0/0/0.

What is the proper way to do this on a ISR 4431?  Thank you.

are you ISR4431 accept ip nat enable command ? 

[NetworkZero]

Yes this is a ISR4431 and the "ip nat enable" command is available under a interface.

Hello
can you post a topology diagram ?

I was able to add "ip nat enable" to both of the interfaces involved but I am not sure how to write the NAT command to translate 10.0.0.0 /24 coming into interface tunnel 1 to a single IP.  The inside interface is gi 0/0/0 and I can have the translated source be the IP of this interface or a IP from it's scope of 10.50.50.0 /24.

Everything that I have tried so far has failed.

My Howtos and Projects: Cisco - NAT Overload on the Loopback (exit with different Public IP)

this way we use LO with IP nat enable to NATing all traffic to LO IP

Hello
Can you post a topology diagram to make it clearer as what you are trying to achieve?
