Hi,

What's the difference if you have a Firewall with NAT that permit (and
filter) inbound connections, or simply a firewall that filter the inbound
connections to your valid-IP-addressed stations?

(...)

Well, the use of NAT is not restricted only to administration or security
pourpose.If you have a limited set of valid addresses and you can't
allocate all of them to your internal network, you may use NAT to solve
this. You put invalid addresses to your internal network and translate them
to a single valid one on the other side.

(...)

See you here...
