NAT Rule Definition: A NAT rule in cybersecurity is a network address translation configuration that specifies how packets should be translated when traversing between private and public IP address spaces.
A NAT rule is a configuration in a network device such as a router or firewall that defines how network address translation (NAT) should be performed. NAT rules determine how incoming and outgoing traffic should be translated between private IP addresses within a local network and public IP addresses on the internet. These rules specify which internal IP addresses and ports should be mapped to specific external IP addresses and ports, allowing for secure and efficient communication between devices on different networks.
