Azure Bastion for accessing VM's in different VNET

Hello Puneeth Raya

No, Azure Bastion does not provide direct access to virtual machines (VMs) in different virtual networks (VNets) simultaneously. Azure Bastion is designed to provide secure and convenient remote access to VMs within the same VNet where it is deployed.

Each Azure Bastion instance is deployed within a specific VNet and subnet, and it enables secure RDP/SSH access to VMs within that VNet. It uses a private IP address from the subnet where it is deployed and establishes a secure connection to the target VMs within the same VNet.

If you have VMs in different VNets and want to access them using Azure Bastion, you would need to deploy separate Azure Bastion instances in each VNet. Each Azure Bastion instance will provide access only to the VMs within the same VNet where it is deployed.

However, if you require centralized access to VMs across multiple VNets, you may consider alternative solutions such as establishing VPN or VNet peering between the VNets to enable connectivity between them. This way, you can connect to the VMs in different VNets using a single VPN gateway or virtual network gateway.

Keep in mind that network connectivity and security considerations, including routing, subnets, and network security groups, need to be carefully planned and configured when connecting VMs across multiple VNets.
