    ip nat inside source list 1 pool NAT-POOL overload
  • access-list 1 permit 10.0.0.0 0.255.255.255
    ip nat inside source list 1 interface serial 0/0/0 overload
  • access-list 1 permit 10.0.0.0 0.255.255.255
    ip nat pool NAT-POOL 192.168.2.1 192.168.2.8 netmask 255.255.255.240
    ip nat inside source list 1 pool NAT-POOL overload
    ip nat inside source static 10.0.0.5 209.165.200.225

Explanation: With the ip nat inside source list 1 interface serial 0/0/0 overload command, the router is configured to translate internal private IPv4 addresses in the range 10.0.0.0/8 to a single public IPv4 address, 209.165.200.225/30.
The other options will not work because the IPv4 addresses defined in the pool, 192.168.2.0/28, are not routable on the internet.
