what is the difference between dynamic NAT and NAT
overload ? and how it works ?

Answer Posted / souvik das

In Dynamic NAT there is more than one Registered/Global IP
addresses in the IP Address pool, Addresses are dynamically
assign with each private IP whenever any host(assignd with
Private IP Add) try to access Internet.

Otherwise NAT Overload is to assign only ONE
Registered/Global IP address to many private IP Add. It's
just "Many to one".
