Certainly! This is, by the way, the whole point of Dynamic NAT (or 
masquerading). Some implementations will  change the sequence numbers, 
or the source ports to  force them to be unique.  Others just trust 
that source ports are generally random enough (combined with dst IP 
and dst port) to tell the connections apart.   By these methods, you 
can have many clients (private/unregistered IPs) and only one or a few 
public/registered IP addresses.

To learn a lot more about general NAT and some vendor specific
stuff, check out this web site:

excellent and very thorough.

within a NAT pool?  Will it reuse IPs already given out or will clients be 
denied access.  Does this depend on the firewall being used or is it a general 
concept?
