> [Bill Stackpole] No. The feature cost is tied somewhat to the
> platform but you need to buy the plus version of IOS. For a 25xx
> series the option is around $900 and you may need to
> add some flash RAM as well.
> 2.) Does the router NAT use the concept of an "inside" address
> and an "outside" address ?
> [Bill Stackpole] Yes, you create a pool of address and/or static
> translation then assign
> interfaces as inside and outside.
