Define the public IP address pool that will be used for CGNAT. This pool should be large enough to accommodate the approximate number of users you expect to have.
Create a NAT pool object to represent the public IP address pool. This can be done using the "ip nat pool" command in the router's configuration.
Define a NAT inside source and a NAT outside source. The NAT inside source is the range of private IP addresses used by your customers, and the NAT outside source is the public IP address pool you defined in step 1.
Create a NAT translation rule using the "ip nat inside source" command. This rule specifies the NAT inside and outside sources, as well as the NAT translation method (e.g. static NAT or dynamic NAT).
(Optional) If you want to enable NAT overload (also known as PAT or Port Address Translation), you can use the "ip nat inside source list" command to specify a list of ports that should be allowed for NAT overload.

Is possible to include ARSs wan IP into nat pool? Or i need to exclude it?
For eg if the asrs NAT outside interfaces ip is 10.20.20.5 /25 than can i make pool that will inclide this ip? For eg the pool will be 10.20.20.1-10.20.20.127
