Homes and Businesses:
When you only have one IP
but you have LOTS of machines
192.168.1.2:100 -> 188.8.131.52:34567
(use same entry for reverse traffic)
OUTSIDE NEVER SEES NET 192.168.1.x, only 184.108.40.206!
Not a problem only because
the internal machines seldom use
a large number of the available ports
-> NO SUCH SERVICE
-> ILLEGAL ADDRESS
No way to access the service.
-> Can’t provide external services from the inside.
(you can but it requires some extra effort
and another software package … more later)
