I have a router with the following configuration and i am not seeing any NAT Translation can you please let me know where is the mistake.
The inside interface is Gigabit Ethernet 2.
I am natting 107.154.50.39 to 10.0.1.142
interface Tunnel0
ip address 192.168.247.29 255.255.255.252
ip nat outside
tunnel source 10.0.0.252
tunnel destination 107.154.40.168

interface GigabitEthernet2
ip address dhcp
ip nat inside
negotiation auto

ip nat pool LAN-NAT 107.154.50.39 107.154.50.39 prefix-length 24
ip nat inside source route-map GRE-NAT pool LAN-NAT

If you are NATing 107.154.50.39 to 10.0.1.142 you should replace the NAT config with:
ip nat inside source static 10.0.1.142 107.154.50.39

I had tested this statement before I was able to see NAT translations coming in but when traffic came from instance back to Internet it was not NAtting.
That is the reason I tried this different config it was not doing any translations
I think this is something to do with tunnel interface NAT

Hi, Can the outside interfaces ping each other?
Do you have an ip route to reach the other side of the GRE tunnel or a router protocol?

The NAT configuration I have given is correct, so it is some other issue - such as a lack of understanding of how your environment works.
Where does this tunnel go to? Is your Internet actually delivered over this tunnel? Do you have a default route pointing to 192.168.247.30?
Perhaps try posting your whole config.
