NAT/PAT Configuration

[bw3481]

I am configuring a routers, and would like to do nat overloading (pat). Is it possible to configure this with only a single outside address ?

Thanks in advance.

Yes it is possible. You can do PAT either on an address you define in a pool or on an interface address.

ip nat inside source list pool test overload

OR

ip nat inside source list interface Fastethernet0 overload

Where is a standard or extended access-list you have configured. You can also use route-maps instead of lists to classify which packets to NAT/PAT.
