Help with nat configuration!!!

I have a cisco 1700 series router.

I am trying to connect trough a serial device and have not configured nat at all.

All my Ips should route through the serial interface which is

so the wan should all traffic coming from the address.

I have a 192.168.0.* ip range in my office.

the lan side of my router fast ethernet 0 is

all private ips should route through the wan side of the router.

Please help on how to configure router

Re: Help with nat configuration!!!

A very basic configuration that should do for you is:

interface serial 0/0

ip address (should be this but check with ISP)

no shutdown

ip nat outside

interface fastethernet 0/0

ip address

no shutdown

ip nat inside

ip nat inside source list 161 interface serial0/0 overload

access-list 161 permit ip

ip route serial 0/0
