Dynamic NAT on routers ???

Hi anyone please help to clarify should I have the following lines on my router;

L1 - ip nat pool filem 210.187.96.1 210.187.96.15 netmask 255.255.255.240

L2 - ip nat inside source list 1 pool filem overload

.

.

.

L10 - access-list 1 permit 172.16.132.0 0.0.0.255

NOTE: 210.187.96.0 - Public IP and 172.16.132.0 - Internal IP addresses

(1) In L1, L2 & L3, does it mean that it 's automatically mapping 172.16.132.1 to 210.187.96.1, 172.16.132.2 to 210.187.96.2 and so on ?

(2) in L2, what does it mean by "overload" ?

Please help out.

Thank you.

Re: Dynamic NAT on routers ???

The answer to your first question is no, it will not automatically map to the same host address.

Oveload enables one global address to be used for multiple local addresses by using different port numbers.
