nattign to Dynamically assigned ip address

[cormon]

i ams setting up a Lab with a cisco 2600 and afew hosts having off this via a switch . Heres my question

When preforming nat on the router is it posssible to specify the interface as the IP ADDRESS pool to be natted to as I dont have a static public address .Is this possible at all even.. thanks

so if i was to issue the following " ip nat pool sample-pool bri 0" and
"ip nat inside source list 5 pool sample-pool" would this work Thanks very much

Hello,

I think the syntax you have in mind does not exist. But overloading (PAT) would accomplish the exact same thing, since your pool, existing of whatever address is assigned to your interface, would consist of one address only anyway.
So I would configure the following:

ip nat inside source list 5 interface bri0 overload
