Hi,
Dynamic NAT is not working with the following config. Could you assist with configuration.
Thanks.

The return packets to your pool addresses are probably being dropped.
Can you change the subnet mask on S0 and the adjacent router to include your NAT pool range? That would fix it. Or you could add a static route on the adjacent router pointing your pool subnet back to 200.200.100.1.
Please rate helpful posts.

It might be easier to PAT your internal address as follows:
ip nat inside source list 1 interface Serial1/0
overload
This will translate all yout internal address to your serial IP using PAT.
