Re: Does ICS or Firewall have a NAT

Well I read somewhere, that a NAT creates a mapping of an intranet computers
request out to the Internet. When a response arrives from the internet, the
NAT looks in its mapping, to which intranet computer it should forward the
response. This mapping is created dynamically and deleted when not needed
anymore. The side effect of this is that the NAT actually works as a kind of
fire wall neglecting all inbound traffic for which it does not have a
mapping. This is all OK and does not require static mapping.
But, if I would set up a server (on the intranet) to be accessible from the
Internet, the NAT would need a static (persistent) mapping to know to which
computer forward the requests coming from the Internet and addressed to the
server.
Please correct me if this doesn't make sens at all.
