You are assigned a project to configure SRX Series devices to allow connections to your webservers. The webservers have a private IP address, and the packets must use NAT to be accessible from the Internet. The webservers must use the same address for both connections from the Internet and communication with update servers.
Which NAT type must be used to complete this project?
Static NAT provides a one-to-one mapping between the private IP address of your webservers and a public IP address. This type of NAT allows the servers to be reachable from the internet using the public IP address and ensures that when the servers initiate connections (e.g., to update servers), they appear to come from the same public IP address. This maintains a consistent IP address for both inbound and outbound connections, meeting the project requirements.
Only static NAT with pool ensures both traffic initiated from inside and outside networks use the same IP address.
