Jumpbox networking

In this post we will review how to connect to Virtual Machine Scale Set instances using RDP for Windows and SSH for Linux.We will cover the following approaches: Connecting directly to virtual machines Connecting through a jumpbox Leveraging Azure BastionNOTE: We will mainly discuss networking part but not detailed steps how to use RDP or SSH, there are already a lot of great articles on these topics. Also, throughout the post most examples are for RDP and 3389 port, however, for SSH case it is mainly just using port 22 instead of 3389.Contents: Connecting Directly To VMs Inbound NAT Pool and Rules Azure Portal View ARM Templates View Network Security Group Establishing Connection Making It More Secure Connecting Through Jumpbox Creating Jumpbox Using Jumpbox To Connect Using Azure Bastion Useful LinksConnecting Directly To VMsLet’s see how we can connect to virtual machines inside of VMSS from outside of the virtual network, for example, from a developer’s machine.NOTE: Here we are discussing the case when VMSS is placed behind a load balancer. If your virtual machines in a scale set have individual IP addresses, then skip the section about inbound NAT pool and rules.To be able to connect to the VMSS we need to check that inbound NAT rules and network security group are configured correctly.Inbound NAT Pool and RulesSince our virtual machines are placed behind a load balancer and all have one public IP address which is assigned to the load balancer, we want to use this IP address to somehow reach RDP 3389 or SSH 22 port of a particular virtual machine.Inbound network address translation rules that are configured on the load balancer help us achieve that. Essentially, inbound NAT rule specifies where the load balancer should forward incoming request arriving at a particular port.What we need: Create a load balancer Inbound NAT Pool Associate VMSS with the this poolWhen creating a resource through Azure Portal, these inbound NAT pool and rules are set up by default but it’s better to check whether they are present especially if you create your resource in a different way.Azure Portal ViewBelow is an example how it looks like for a load balancer for VMSS with two instances. For instance, if we open one of the rules we’ll see a rule which states that all requests over TCP which arrive at IP 20.69.134.228 at port 50002 should be forwarded to VMSS instance 2

Jumpbox Genesis KitThis is a Genesis Kit for the jumpbox-boshrelease. It creates a VMwith persistent users, that can be used as a starting point for connectingto infrastructure internal to a VPC/Virtual Network in the IaaS.The jumpbox contains a multitude of utilities useful for managing and interactingwith BOSH, Cloud Foundry, Concourse, and other related components.Quick StartTo use it, you don't even need to clone this repository! Just runthe following (using Genesis v2):# create a jumpbox-deployments repo using the latest version of the jumpbox kitgenesis init --kit jumpbox# create a jumpbox-deployments repo using v1.0.0 of the jumpbox kitgenesis init --kit jumpbox/1.0.0# create a my-jumpbox-configs repo using the latest version of the jumpbox kitgenesis init --kit jumpbox -d my-jumpbox-configsOnce created, refer to the deployment repo's README for information on creatingValidationThis kit bundles an inventory errand, on the main jumpboxinstance, so that you can validate the installation and also getinformation about the versions of things installed.

For dev and test purposes but it is better not to have such thing in production.Therefore, we should restrict from where connections can be established. For example, we could only allow connections from our VPN by specifying a range of addresses associated with it. Read more about NSG rules in documentation.Another approach to consider is to connect to the virtual machines through a jumpbox which we will discuss in the next section.Connecting Through JumpboxThe idea is quite simple, just create a dedicated machine (jumpbox) in the same virtual network that will have connectivity to other virtual machines. All RDP/SSH connections should go though this jumpbox.This way we don’t need to expose all machines to the Internet and can also implement tighter security measures and audit only on this jumpbox machine.Let’s see how we can create a jumpbox to connect to our VMSS instances.Creating JumpboxNow we are going to create a virtual machine and place it in the same virtual network. Remember that network security group by default contains an inbound rule that allows requests that are issued from the same virtual network.So, to create a jumpbox we need to: Create a virtual machine Associate public IP address with this VM Place the VM in the same virtual network (any subnet would work) Open RDP/SSH port using NSG rulesNOTE: This setup is done for us automatically when creating though Azure Portal, the only thing needed is to select the correct virtual network. That’s why we won’t cover these steps in detail.If you want to do it using ARM templates, I would recommend creating a sample resource though Azure Portal and then using “Export template” tab, it would serve as a very good starting point.IMPORTANT: For production use you should allow remote connections only from known IP addresses, it can be achieved using network security group rules.Using Jumpbox To ConnectNow our path to the desired virtual machine is a bit longer and goes though the jumpbox: Connect to the jumpbox: use public IP address which we can find in “Connect” tab of the virtual machine resource. Connect to VMSS instance from jumpbox: use private IP address of a VMSS instance which could be found in “Connect” tab of the corresponding instance.And that’s basically it!Using Azure BastionLastly, let’s talk about Azure Bastion. Essentially, this is a managed version of the jumpbox approach discussed in the previous section.Here are the main points: Managed PaaS
