Final answer:
To configure Server1 as a NAT server after installing Routing and Remote Access, the next step is to Add New Interface to set up the public and private interfaces for traffic translation and basic security.
Thus, the correct option is A.
Step-by-step explanation:
After installing Routing and Remote Access on Server1 to use it as a NAT server, the next step you should configure is to Add New Interface. This involves adding the interfaces that will participate in NAT, where one will be the public interface connected to the external network with a public IP address, and the other will be the private interface connected to the internal network with private IP addresses.
The process ensures that outbound traffic from the private network can be translated to a public IP address, allowing communication over the internet, while also providing basic security by hiding internal IP addresses.
Configuration steps typically include:
- Opening the Routing and Remote Access management console.
- Navigating to the NAT/Basic Firewall node under the server where NAT will be configured.
- Right-clicking on the NAT/Basic Firewall node and choosing "New Interface".
- Selecting the desired network interface and configuring it with either public or private settings, depending on the network it is connected to.
- Configuring additional options such as address pool and translation settings as needed.
Therefore, the correct option is A.Add New Interface.
