Some NAT question

Hi all,

Got a question..hope you can answer.

if i configure nat on my serial in interface(connecting to internet), do i need to configure my fast e too so that the traffic going back to the internet will be the original ip ?

 
Not sure how exactly your router is configured, but we have the ISP's IP on the serial interface (outside), and our own public IP on the ethernet interface (inside).
What kind of router and Internet connection do you have?
 
Regardless, your WAN interface will have a public IP. Your internal machines will have local non-routable ip which in turn will get translated to the public IP when you use an application on the internet.

Traffic will appear to come from your 'original' ip, without you having to do anything else but setup NAT.

What are you trying to do?
