Cloud Service VM connect to onprem SQL server

Question

Is there a way to setup site to site tunnel from Azure Cloud Service network to on-prem?
I have the Site to site tunnel setup to our Azure vnet and on-prem and that works fine.
The problem is that our Cloud Service network is outside the Azure vnet range and I'm not sure if there is a way to connect Cloud Service VM (Web) to our on-prem SQL server.

Any help would be appreciated, thank you.

Answer 1

Sure you can you have to use Virtual Network Gateway and build VPN Site-to-Site with your on-perm firewall

I figured it out. Cloud Services uses Classic Vnet and I found the documentation how to setup S2S tunnel with classic virtual networks.

Answer 3

My site-to-site tunnel from on-prem to Azure Vnet (IaaS) was already setup and running fine.
The problem is that my Web VM was setup under "Cloud Service" (PaaS) and it is completely out of our Vnet range. I believe that's why I can't access it from on-prem network.
I'm I missing a step where I would need to allow vpn traffic to 'Cloud Service' network or Web Server? Since it's under Cloud Service I don't have a lot of control over it.
