Instead, devices should be designed to do outbound calls only (still supporting two-way communication once the communication channel is established).Ī possible solution is bringing local devices to the Cloud VNet and its subnet! Local devices should not expose inbound ports (like opening an SSH port) because this would be an open invitation to hackers. We do not want to expose our local device to the cloud in a public way. your security officer, company policies, penetration testers, or your mom □ Why securing the connection to local client devices, the basicsįrom the Jump box, we want to connect to one or more local client devices. At the end of this blog post, we will discuss some considerations. This post must be seen as an introduction to explain the concepts of a VPN connection together with a jump box. #EASYVPN NETWORK EXTENSION DUPLICAT SUBNETS SERIES#Note: although this solution is known to be secure, these series of posts only show the minimal viable solution, likely not to be fit for every occasion. ![]() If you have not created the Bastion solution yet, please first check out what is created in the previous blog post. ![]() Note: We will expand the solution we created already in part one. We will dive into creating a point-to-site VPN connection, generating certificates to secure the communication, and attaching various VPN clients, including one running on OpenVPN. #EASYVPN NETWORK EXTENSION DUPLICAT SUBNETS HOW TO#In this blog post, we will discover how to connect local devices (both running Windows or Ubuntu) from the cloud in a secure way, making use of the already existing VNet and the Bastion connection: Part one ended with a private VM in the cloud which was accessible using a secure Azure Bastion connection: This blog is part two of a series about setting up a jump box in Azure to access local devices from the cloud. an RDP or SSH session.įor this, we do not want to create an inbound port in the firewall offering a public inbound session this makes the devices vulnerable to attacks from the outside world. Although these devices are designed to be robust and probably are configurable in a zero-touch manner, sometimes it is still needed to log in to these devices using e.g. Azure IoT devices send telemetry to the cloud in a secure and reliable way. ![]()
