#ip nat inside source list 1 interface s0 overload

! in the serial interface

Re: basic nat configuration

Hi there,

interface serial 0/0

ip nat outside

interface fastethernet0/0

ip nat inside

ip nat inside source list 10 pool wan overload

access-list 10 permit 192.168.40.0 0.0.0.255

access-list 10 permit 192.168.41.0 0.0.0.255

ip nat pool wan 56.253.124.23 56.253.124.23 prefix-length 24

Note: I assumed that the 56.253.124.23 is /24.

If the serial interface is the same interface having the ip address 56.253.124.23 that you want to NAT with, you can use:

ip nat inside source list 10 interface serial0/0 overload

HTH,
