Hello All,

Thanks so much for your explaining.

Good question.

NAT stands for Network Address Translation.

"Network Address Translation allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network."

It is a table (service) in your router that translates a request to a server on your private subnet, from a public IP address. So, in other words, if you have a record in DNS of SOMESERVER.SOMEDOMAIN.com that has a public routable IP address of 22.43.22.xx, your NAT would listen on the IP address, and translate those requests to some IP address that is on your subnet (nonroutable), like 192.168.0.10.

I hope I have explained this well enough.

NO. NAT is for translation, firewall for permission of services and connection types.
