Need Answer .Please clear my doubt

Hi ! I am trying to configure Port Address Translation using the commands below. What I am trying to accomplish is to overload the IP 170.168.2.1 which is also int s0/0's IP address. I am not sure if the it the command "ip nat inside source list 1 interface s0/0" would equal the first two lines of the commands below.

ip nat inside source list 1 pool PAT_POOL overload
ip nat pool PAT_POOL 170.168.2.1 170.168.2.1 netmask 255.255.255.0

access-list 1 permit 10.1.1.0 0.0.0.255

int e0/0
ip add 10.1.1.10 255.255.255.0
ip nat inside
no sh

int s0/0
ip add 170.168.2.1 255.255.255.0
ip nat outside
no sh

access-list 1 permit 10.1.1.0 0.0.0.255

Please bear with me as I can't think of any way of verifying this. I am just using gns3 to study for this.

Thanks a lot.
