Detailed explanation-1: -Network Address Translation: A form of Internet security that conceals internal addressing schemes from external(public) networks ie.. internet. Translates private IP address to public IP addresses then back again.

Detailed explanation-2: -NAT stands for network address translation. It’s a way to map multiple private addresses inside a local network to a public IP address before transferring the information onto the internet. Organizations that want multiple devices to employ a single IP address use NAT, as do most home routers.

Detailed explanation-3: -Symmetric NAT The combination of one internal IP address plus a destination IP address and port is mapped to a single unique external source IP address and port; if the same internal host sends a packet even with the same source address and port but to a different destination, a different mapping is used.

Detailed explanation-4: -Firewall NAT policies collect rules to provide NAT address and port translation for source and destination addresses, including match rules for addresses and protocols, and translation rules for source and destination. You can attach a NAT policy at the device level, a route domain, or to a virtual server.
