Ingress Traffic from Azure Bastion: Azure Bastion will reach to the target VM over private IP.This is the subnet that contains the target virtual machine that you want to RDP/SSH to. For this reason, we recommend enabling port 80 outbound to the Internet. Egress Traffic to Internet: Azure Bastion needs to be able to communicate with the Internet for session, Bastion Shareable Link, and certificate validation.For this reason, Azure Bastion needs outbound to 443 to AzureCloud service tag. Egress Traffic to other public endpoints in Azure: Azure Bastion needs to be able to connect to various public endpoints within Azure (for example, for storing diagnostics logs and metering logs).This enables the components of Azure Bastion to talk to each other.

Egress Traffic to Azure Bastion data plane: For data plane communication between the underlying components of Azure Bastion, enable ports 8080, 5701 outbound from the VirtualNetwork service tag to the VirtualNetwork service tag.If you are using the custom port feature as part of Standard SKU, the NSGs will instead need to allow egress traffic to other target VM subnets for the custom value(s) you have opened on your target VMs. The NSGs need to allow egress traffic to other target VM subnets for port 3389 and 22. Egress Traffic to target VMs: Azure Bastion will reach the target VMs over private IP.This enables Azure Load Balancer to detect connectivity Ingress Traffic from Azure Load Balancer: For health probes, enable port 443 inbound from the AzureLoadBalancer service tag.Ingress Traffic from Azure Bastion data plane: For data plane communication between the underlying components of Azure Bastion, enable ports 8080, 5701 inbound from the VirtualNetwork service tag to the VirtualNetwork service tag.This enables the control plane, that is, Gateway Manager to be able to talk to Azure Bastion.

Ingress Traffic from Azure Bastion control plane: For control plane connectivity, enable port 443 inbound from GatewayManager service tag.

Note that the source can be either the Internet or a set of public IP addresses that you specify. Port 3389/22 are NOT required to be opened on the AzureBastionSubnet.

Ingress Traffic from public internet: The Azure Bastion will create a public IP that needs port 443 enabled on the public IP for ingress traffic.

AzureBastionSubnetĪzure Bastion is deployed specifically to AzureBastionSubnet. Omitting any of the following rules in your NSG will block your Azure Bastion resource from receiving necessary updates in the future and therefore open up your resource to future security vulnerabilities. If you choose to use an NSG with your Azure Bastion resource, you must create all of the following ingress and egress traffic rules.
