Public IP to Public IP NAT


We are using Public IPs inside our networks due to some legacy network in place,we have a team of users who use this public IP while going out ,I would like to hide and NAT these as one Public IP while going out.

I have done NAT from Private to Public which is common scenario in any organisation.

Can someone guide on this on Public to Public NAT, ( I will be doing this on a Cisco FWSM )

It's just the same.  They're just numbers.

Agreed, as long as the subnets don't overlap, And sorry to be a pendant but you want to PAT the internal addresses to an external address (PAT=Many to One, NAT=One to One, (as a general rule of thumb, because this can be broken)).

Basically I would say PAT as I have group of 6 users using the Public IPs inside LAN and I would like to Hide these IPs  under one public IP while going out.

I prefer NAT and then PAT overload when there are insufficient addresses in the pool.
