Network Address Translation (NAT) is a technique in which the source and/or destination addresses of IP packets are rewritten as they pass through a router or firewall. It is commonly used to enable multiple hosts on a private network to access the Internet using a single public IP address.
Only static NAT entries are supported in Manager. Consider the following scenarios to explain the use of NAT in Manager:
Scenario 1: Manager using a private IP address
To establish the Manager-Sensor communication, configure the Manager's public IP address (external reachable) on the Sensor by using the following CLI command:
set manager IP
Note
To support multiple NIC cards, you need to select the respective local IP address in Sensor Communication Interface during Manager installation.
Note

Scenario 2: Sensor using a private IP address
The Manager-Sensor communication works as usual. You need not make any changes to the setup to achieve this.
