Just want to see if I can achieve this using Azure Point to Site networking.
Network A
Closed enterprise network (private) cannot be accessed from outside (internet) and I have On-Premises database and other resources accessible on a machine (Machine A) within this Network.
Question
If I create a point to site Azure network from the Machine A to Azure and add VM's to Azure network, can I access the On-Premises database from the VM in Azure Virtual network?
Thanks
If I create a point to site Azure network from the Machine A to Azure
and add VM's to Azure network, can I access the On-Premises database
from the VM in Azure Virtual network?
Yes, you can access the On-premise database from Azure VM.
I did a test in my Lab. I found that after connecting your on-premise machine to Azure P2S VPN, you would get a Virtual IP from the P2S address pool:
So, if you want to access your on-premise machine from Azure AM , you need to use this virtual private IP address.
I can use this VIP to access the on-premise machine :

You can deploy and configure Azure Bastion from the Azure Portal itself. Ensure you fulfil the specified prerequisites before getting started.
In the Azure portal, you first have to create a Bastion host in your virtual network. It takes about 5 minutes for the Bastion resource to be created and deployed.
After deploying the resource, you connect to a VM via its private IP address using the Azure portal. Your VM does not need a public IP address or special software. Once the service is provisioned, the RDP/SSH experience is available to all of the virtual machines in the same virtual network. Refer to this tutorial for a detailed walkthrough.
Is there any way to use Azure Bastion to connect to on-prem systems as well as Azure virtual machines?
I have a hybrid cloud environment where some key machines are on-prem and some are Azure VMs. The Azure VNet is extended with a VPN tunnel so the azure VMs can talk to the on-prem machines.
In Googling my question, I was not able to find much...
The official page for Azure Bastion describes it as '''Azure Bastion is provisioned directly in your Virtual Network (VNet) and supports all VMs in your Virtual Network (VNet)'''
This page talks about hybrid envrionments https://blog.ahasayen.com/introducing-azure-bastion/ , saying:
'''You might also have some sort of hybrid connectivity with your on-premises network and when you are outside the office, you use point to site VPN to securely access your VNET, which is the ideal situation.'"
I am aware of Azure Arc which is currently in preview. Would something like that be appropriate to make this work?
My overall questions are:
Am I totally barking up the wrong tree here? Is my understanding off?
Is it possible to use Azure Bastion to access an on-prem server on an extended VNet?
Thanks in advance!
As far as I know, currently, it's not possible to use Azure Bastion to access an on-prem server on an extended VNet. You only could use Azure Bastion to access all the VMs in the VNet which has AzureBastionSubnet. Refer to this blog
Azure Bastion resides on the same virtual network (VNet) as the
servers accessed and only connects to one VNet.
Actually, you can have a private and securely RDP/SSH connection between your on-premise server and Azure VM via a VPN gateway, you just can not RDP/SSH on-premise server via Azure portal. If you need this feature with Azure Bastion, it's welcome to give feedback or upvote these similar feedback1 and feedback2.
Hope this could help you.
This is now possible via the new capabilities introduced in Azure Bastion Standard Tier.

I have an Azure Cloud Service (Worker Role) that needs to connect to my Azure SQL database and also connect to an external database.
In development the external database was on the public Internet and connectivity was not a problem.
However, the solution now needs to be deployed in a production environment and access to the external database is to be restricted by setting up a Virtual Network.
The Cloud Service, when deployed in the Virtual Network, gets an IP from the subnet, but seems to become inaccessible to the outside world, and is not connecting to the Azure SQL database (I also cannot RDP to it).
This seems to be beyond my level of understanding of networking, but I don't see why it should lose access to its neighbours in the Azure environment.
What am I missing? Do I need to get involved with Endpoints? Is the Virtual Network misconfigured?
Thanks in advance.
Your question is quite vague, in terms that it does describe the whole picture in the best possible way. Let me put my answer based on my understanding about your issue.
First of all - Azure virtual Network is Virtual Network. It is designed to enable secure cross-premisses connectivity with Windows Azure Data Center.
When you deploy a proper PaaS Cloud Service (Worker Role / Web Role) in a Virtual Network, the role instances get IP Addresses allocated from the defined DHCP pool (the VNet Definition).
When you deploy any service in an Azure Virtual Network you have to take care of Name Resolution! Meaning that, if you do not provide a proper DNS Server, your cloud instances will not be able to resolve any address. That includes Azure SQL Database servers. More on Name Resolution can be read here.
Next, but not less important - Azure SQL Database servers are not part of, and, as of March'2013, cannot be added to Azure Virtual Network!
The last statement means that in order for your Worker Role to access Azre SQL Database server, you need to provide a proper DNS server in your Azure Virtual Network.
And lastly, when you deploy a PaaS service into a Virtual Network, in order to access it via Remote Desktop need to:
* Properly enable and configure RDP extension. it will anyway create Input Endpoint. But this is the only way to enable RDP on PaaS right now;
* You could probably enable RDP via PowerShell startup script and access RDP via the VPN tunnel for the Virtual Network - say you configured a Site-to-Site or Point-to-site VPN for your Azure VNet.
Check the building cross-premises Virtual Network guide here.
Scenario:
I have a website on Windows Azure. That website needs to connect to a (new) Azure VM.
I have done the following:
Created new Virtual Network on Azure
Added the VM to the Virtual Network, and it does get an IP in the virtual network.
I have configured the appropiate Endpoint for the VM (Public/Private port).
Now, how do I "connect" the Azure website to the same virtual network, such that my .NET code in the website can create a TCP connection to the VM on it's IP on the Virtual Network ?
This is now possible. Be sure to use the NEW Azure Portal. For details, check out:
http://azure.microsoft.com/blog/2014/09/15/azure-websites-virtual-network-integration/
Currently you cannot connect/add Azure Web Site to a Virtual Network. You can only add VMs and Cloud Services to a Virtual Network. However this is a demanded feature and I believe we will see it in the future releases of the Web Sites service (my speculation).
The key here is to create the Virtual Network before the Virtual Machine and then place the VM in the VN during it's creation. The article here gives instructions moving a VM into a VN.

I have a Web role on Azure. I would like to allow only my people to access the web role.
I have found post to manual/code to restrict IPs to access the role. I would like to create firewall way(something like SQL Azure's firewall) to block/allow IPs.
I could not find any setting in Azure console. please help.
If you publish your endpoint on the Internet through the Windows Azure load balancer, there is no option in place to define firewall rules on Azure.
But you can secure access to VMs created using either Windows Azure’s Infrastructure as a Service (IaaS) technology or its Platform as a Service (PaaS) technology through the Windows Azure Virtual Network service.
Windows Azure Virtual Network lets you create a logical boundary around a group of VMs, called a virtual network or VNET, in a Windows Azure datacenter. It then lets you establish an IPsec connection between this VNET and your local network.
For more information see Networking, Windows Azure Networking, Windows Azure Virtual Network, Create a Virtual Network for Cross-Premises Connectivity, Create a Virtual Network in Windows Azure.
About the cost of this service: Windows Azure Virtual Network is currently (February 2013) available in preview at no charge. Once the service becomes generally available you will be charged if you create a hardware VPN connection between a Virtual Network (VNET) and your VPN gateway. The charge will be for each hour that the VPN connection is provisioned and available (called the “VPN connection hour”). All data transferred over the VPN connection is charged at Window Azure’s standard data transfer rates. You can use the pricing calculator for a simulation.
