By masking the IP addresses of internal computers from the Internet Network Address Translation (NAT) is the process where a network device, usually a firewall, assigns a public address to a computer (or group of computers) inside a private network. The main use of NAT is to limit the number of public IP addresses an organization or company must use, for both economy and security purposes. Mar 28, 2019 · A NAT firewall will not protect you from a man-in-the-middle attack, in which a hacker running a fake wifi hotspot captures all of your traffic by posing as the servers that you want to connect to. There are still plenty of security weaknesses in any connection that NAT firewalls cannot protect you from. Nov 10, 2014 · A.

Microsoft's Secure network address translation (SNAT) is part of Microsoft's Internet Security and Acceleration Server and is an extension to the NAT driver built into Microsoft Windows Server.

With NAT, IP addresses in the internal network are not routable from the external one; the comparison with a firewall is not completely correct, because a firewall filters network traffic which, ordinarily, should be able to flow through it; NAT reshapes traffic that ordinarily shouldn't be able to flow that way, allowing it to flow under some specific rules.

Because of the way in which NAT devices translate network traffic, you may experience unexpected results when you put a server behind a NAT device and then use an IPsec NAT-T environment. Therefore, if you must have IPsec for communication, we recommend that you use public IP addresses for all servers that you can connect to from the Internet. In your network, the best way to find out if your using NAT is to gain access to your gateway/firewall and view its configuration. If you see your internal addresses I.E. 10.0.0.x being translated to something else, I.E. 192.168.0.x, then it's most likely you're using NAT. NAT is a study in itself and extremely interesting.
