Introduction:

For users requiring a secure and dedicated remote access solution, such as L2TP/IPsec (PSK) VPN, efficient deployment of Virtual Private Network (VPN) infrastructure is a critical capability. NovaCloud, which offers affordable, reliable, and highly secure cloud computing for everyone, facilitates the provisioning of these specialized networking services directly through the Customer Portal.
To accelerate the deployment of remote access solutions, the Customer Portal provides the Create Instance from One-Click Application feature. This specialized method streamlines the launch of a Cloud Instance pre-configured with the required software. Specifically, to deploy L2TP/IPsec (PSK) VPN, users must select the Remote-Access VPN category during the instance creation process.
This guide provides a professional, step-by-step walkthrough detailing how to launch a Cloud Instance containing your desired remote-access component (L2TP/IPsec (PSK) VPN) using the One-Click Application feature in the NovaCloud Customer Portal, ensuring you can quickly establish a functional and secure VPN connection.

Prerequisites:

The user must have access to the Customer Portal.
The account balance must contain sufficient credit/points
The user must select an existing Public Key during the creation process. If you do not have any keys yet, you are required to generate or import one before proceeding.

Step-by-step Guide:

Step 1: Click NovaCloud

Locate and click on the NovaCloud section in the left-hand navigation menu to access cloud resources.

Step 2: Click Cloud Instances

Navigate to the management interface for your virtual machine resources.

Step 3: Click Launch Project

Initiate the process for deploying a new cloud resource.

Step 4: Click Create Instance from One-Click Application

Select the accelerated deployment method designed for provisioning instances pre-installed with your chosen application (database).

Step 5: Choose Category as Remote-Access VPN, Select L2TP/IPsec (PSK) and Choose the Version

Ensure the Category is selected as Remote-Access VPN.
Select the specific VPN application, L2TP/IPsec (PSK)
Choose the required version you wish to deploy

Step 6: Select a Plan

Choose the appropriate resource plan (CPU, RAM, data transfer limits) for your database instance.

Important Note ⚠️: You can optionally choose a RAM Optimised plan if your needs require higher performance characteristics, which is particularly suitable for data storage applications.

Step 7: Select Your Storage and Key in Volume Size

Define the volume size for your storage.

Important Note ⚠️: The volume size must be at least 10 GB and no more than 1000 GB in size.

Step 8: Select Project to Attach, Key in Name Instance and Click Continue

Associate the instance with an existing project (if desired) and provide a unique name for your instance.

Important Note ⚠️: The instance name can only contain letters, numbers, underscores and dashes, and must be between 1 and 60 characters long.

Step 9: Select Public Key, Enter VPN Username and Preshared Key and Copy all Information

Select the Public Key
Enter the VPN username and preshared key
Copy all provided information

Important Note ⚠️:

– The username needs to be between 4 and 15 characters long, alpha-numeric, and can include periods, underscores, and dashes.

– The preshared key needs to be between 8 and 32 characters long and alpha-numeric

Step 10: Configure Port of Security Group and Security Group Rules

Define which ports should be opened in the security group for the database (e.g., specific TCP ports)
Apply predefined security rules (e.g., allowing SSH or HTTP/S traffic).

Step 11: Assign Security Groups, Select Network to Attach and Click Create

Apply specific existing security groups (if needed)
Select the network(s) to attach.

Important Note ⚠️: You can skip the assigned security group system and the system will auto assign a security group for you. Attaching a private network automatically assigns a private IP to ensure secure, private, and performant communication, and network transfers between private IP addresses are not metered.

Step 12: Scroll and Click Create

A confirmation pop-up will appear. Review the specifications, scroll to the bottom, and click Create to launch the instance.

Step 13: Click Instance

Click the “Instances” button in the confirmation pop-up to navigate to the list of Cloud Instances.

Step 14: Success

Your request to launch the instance has been queued, and the provisioning process is underway (status “Creating” or “Active”).

Conclusion:

By successfully navigating the detailed instructions, you have efficiently utilized the Create Instance from One-Click Application feature to deploy a secure L2TP/IPsec (PSK) VPN instance within the NovaCloud Customer Portal. This process involved selecting the appropriate category (Remote-Access VPN) and configuring critical security parameters such as the VPN username and preshared key.

Upon confirming the cloud instance creation by clicking “Create”, your request to launch the VPN instance was queued for provisioning. You can confirm its initiation by clicking “Instance”, where the status will appear as “Creating” or “Active”.

It is crucial to remember the operational constraints of the service: All instances are charged hourly. Credits are deducted immediately on a prorated basis until the end of the current hour, after which standard hourly charges will apply thereafter. For security purposes, outgoing SMTP traffic is restricted.
