Detailed explanation-1: -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-2: -Static NAT is of the types of NAT that is used for One-to-One Translation of Ports or IP Addresses. In other words, for example in this NAT type, one Private IP Address is mapped to one Public IP Address.
Detailed explanation-3: -While static NAT is a constant mapping between inside local and global addresses, dynamic network address translation allows you to automatically map inside local and global addresses (which are usually public IP addresses).
