Hi everybody!
I am trying to make NAT configurations on the following topology:
After reading various articles and watching some tutorials, I seemed to have finally found a way to make configurations using following inputs:
However, Simple PDU checks have failed and I noticed that outside local and outside global addresses are not shown. I will be grateful for any suggestions on how to fix this

Hello @ket14pril14 ,
>> Yes, you are right subnet 10.0.0.0/25 is defined nowhere. I didn't particularly understand what you meant by "IP 129.55.18.1/30 you can nat to it". Did you mean the following natting?
You could use a trick like adding 10.0.0.0/25 as a secondary address on the serial interface
int serial0/0/0
ip address 10.0.0.1 255.255.255.128 secondary
Alternatively you can create a loopback interface
int loopback 10
desc used for NAT
ip address 10.0.0.1 255.255.255.128
no shut
this to be able to use your previous NAT commands
Hope to help

Hello @ket14pril14
It should be
ip route 20.0.0.0 255.255.255.128 129.55.18.2, no ?

Hello @ket14pril14 ,
you have configured static source nat entries this is why you don't see anything under Outside local and Outsid global this is not an issue.
Where is defined your public IP subnet 10.0.0.0/25?
your network diagram shows a serial with a different IP 129.55.18.1/30 you can nat to it .
Edit:
M02@rt37 is spot on your static route should be referring to the remote public subnet 20.0.00/25 not your local one
Hope to help

Yes, you are right subnet 10.0.0.0/25 is defined nowhere. I didn't particularly understand what you meant by "IP 129.55.18.1/30 you can nat to it". Did you mean the following natting?
The first router:
The second router:
