Hi,
Following is my router config.
R1
!
interface FastEthernet0
ip address 201.x.x.x 255.255.255.248
ip nat out side
!
interface FastEthernet1
ip address 172.16.1.1 255.255.255.0
ip nat inside
!
ip nat pool OFFICE 201.x.x.x 201.x.x.x netmask 255.255.255.252
ip nat inside source list 10 pool OFFICE overload
!
access-list 10 permit ip 172.16.1.0 0.0.0.255
We get another 202.x.x.x/30 ip address from ISP and I would like both /30 to be NAT. how to config the router?

Will you receive the new address on the same fa0 interface ?

1) You need to configure a secondary IP address on interface FastEthernet0 that is part of the 202.x.x.x/30 network.
2) Create a new pool
3) Create a new list
If you want to load balance between the 2 NATs, you can break the current ACL as follow:
no access-list 10 permit ip 172.16.1.0 0.0.0.255
access-list 10 permit ip 172.16.1.0 0.0.0.127
access-list 20 permit ip 172.16.1.128 0.0.0.127
interface FastEthernet0
ip address 202.x.x.x 255.255.255.252 secondary
ip nat pool OFFICE-202 202.x.x.x 202.x.x.x netmask 255.255.255.252
ip nat inside source list 20 pool OFFICE-202 overload
