Hello All,
Can you explain me what is NAT Router? and Is that NAT Router the same with Firewall?
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.
