How many types of NAT can generally be configured on FortiGate devices?

FortiGate devices typically support two main types of NAT: Static NAT and Dynamic NAT.

Static NAT involves a one-to-one mapping between an internal private IP address and a public IP address. This type of NAT is often used for hosting services such as web servers, where traffic needs to consistently go to the same internal address.

Dynamic NAT, on the other hand, creates a pool of public IP addresses to be assigned to different internal devices on an as-needed basis. This approach is useful for organizations that do not require a consistent public address for each device but need to connect to the internet intermittently.

By understanding these two types of NAT configurations and their applications, you can effectively manage how internal devices communicate with external networks while maintaining control over IP address usage and enhancing security.
