AZURE BASTION LOGGING HOW TO

Azure Portal Viewīelow is an example how it looks like for a load balancer for VMSS with two instances. When 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.

Create a load balancer Inbound NAT Pool.

Essentially, inbound NAT rule specifies where the load balancer should forward incoming request arriving at a particular port. Inbound network address translation rules that are configured on the load balancer help us achieve that. Since 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. To be able to connect to the VMSS we need to check that inbound NAT rules and network security group are configured correctly. If your virtual machines in a scale set have individual IP addresses, then skip the section about inbound NAT pool and rules. NOTE: Here we are discussing the case when VMSS is placed behind a load balancer. Let’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. 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.

NOTE: 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.

Connecting directly to virtual machines.

Bear in mind that this subnet will need to be able to route to the servers you want to connect to.In this post we will review how to connect to Virtual Machine Scale Set instances using RDP for Windows and SSH for Linux. It is key that you create a new subnet called AzureBastionSubnet. Fill out the requisite parts of the form.

Creating the Bastion ServiceĪs it is a preview service you’ll need to use the preview URL. Graphical representation of Azure BastionĬontinue reading to see how to create an Azure Bastion host and use it to connect to your VMs.

There is a public IP attached to the service inside that dedicated subnet, however, you can factor that into your overall VNet design. Your remote session is then launched using HTML 5 over port 443 in a browser window. So, instead of launching your remote client and making a connection, you log into the Azure portal (which allows MFA and has granular built-in RBAC), and use the Bastion connection function. You get the advantages of Microsoft managing the underlying infrastructure and protecting it with state of the art security.Ĭurrently only available in a limited number of regions the service is created within a VNet in your Azure fabric deployment using a dedicated subnet with an attached public IP. Fully PaaS, it’s a service hosted within your Azure tenant. It allows you to “remote” onto you servers via HTML5 without an RDP or SSH client. This is a new service currently in preview. So what’s the answer? There are several depending on the services you use and what you need to access. You can see from the above diagram that the jump box(es) in question require a considered design that is likely to include logging, monitoring, backup, site recovery and security compliance. Typical jump box configuration from on-premises to Azure for support and admin staff RDP and SSH need both a client and a server configured to accept these connections.

RDP / SSH are two of the most prolifically attacked ports for both source and destination.

They need a significant level of protection, monitoring and administration.

However, they also represent a significant hole in the security perimeter of your network for two reasons. They prevent direct access and can protect them from exposure to the internet. Jump boxes are generally used to limit this special and privileged access to your servers. A server / service on your network that serves as a gateway for gaining remote desktop access (SSH and/or RDP) to your servers for administration.Ī protective barrier to hide your servers behind when remote desktop access is required.
