6 Configure N2WS with CloudFormation

The process to configure N2WS to work with CloudFormation is a single stream that starts with subscribing to N2WS on the Amazon Marketplace and ends with configuring the N2WS server.

N2WS provides a number of editions all of which support CloudFormation. An IAM role will automatically be created with minimal permissions and assigned to the N2WS instance.

11. Complete the Stack Details and Parameters. For Inbound Access CIDR, security groups act as a firewall for associated instances, controlling both inbound and outbound traffic at the instance level. Configuring Inbound Access CIDR allows you to add rules to a security group that enables you to connect to your Linux instance from your IP address using SSH:

• If your IPv4 address is 203.0.113.25, specify 203.0.113.25/32 to list this single IPv4 address in CIDR notation. If your company allocates addresses within a range, specify the entire range, such as 203.0.113.0/24.

• If you specify 0.0.0.0/0, it will enable all IPv4 addresses to access your instance using SSH.

• For further details, refer to “Adding a Rule for Inbound SSH Traffic to a Linux Instance” at https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/authorizing-access-to-an-instance.html
