Modify the Network rule under Networking / Network Rules and add ‘Internal’ to the source network and ‘Azure’ to the destination network.

The automatically created Network Rule and Access Rule allow only one way initiated traffic.

Use Perfect Forward Secrecy (PFS): Not selected.

Session key / Generate a new key every: Both enabled.

Authenticate and generate a new key: 28800 seconds.

Diffie-Hellman group: Group 2 (1024 bit).

Under Connection / IPsec Settings ensure the following is set:.

Address ranges: Leave the external interface and add the internal network ranges that need to communicate over the VPN.

Access rule: Create an access rule and select ‘All outbound traffic’.

Network rule: Create a route relationship and add other networks if required.

Remote address ranges: Leave the Azure IP address and enter the Azure network range created earlier for example 10.4.0.0 to 10.4.255.255.

Use pre-shared key for authentication: Enter Shared Key provided earlier.

Local VPN gateway IP address: enter the TMG external IP address.

Remote VPN gateway IP address: enter the Azure Virtual Network gateway provided earlier.

Choose ‘IP Security protocol (IPsec) tunnel mode.

Remote Access Policy (VPN) / Remote Sites / Create VPN Site-to-Site Connection.

I used the content of this massive MSDN forum post to create the IPsec site-to-site VPN and get traffic flowing with the TMG configuration information coming from David Cervigon.

Disable RPC strict compliance and restart TMG firewall service.

Change the TMG network card MTU to 1350.

Make sure the TMG server has hotfix KB2523881 installed.

Modify TMG network rule and access rule.

Setup TMG IPsec with a supported configuration.

The summary of the things I needed to change are:

Create TMG IPsec site-to-site VPNĭuring the setup of the TMG VPN I had a few times where I thought I had it working only to hit another stumbling block. Once the gateway is created, take note the IP address and Shared Key and we can move on to the TMG configuration. I haven’t seen any documentation on how it works, but I suspect it is spinning up a VM in the background to act as the Azure VPN endpoint. Starting the gateway can take a long time. Hopefully this is something that will be available once these services are out of beta. It is important to note that once you have created the Virtual Network and deployed a Virtual Machine the configuration cannot be modified, other than adding subnets. 4 address for your subnet and also add an on-premise DNS server for example 192.168.0.1 For the DNS question (step 6 in the tutorial) enter the. The first VM deployed to each subnet will get the. If you will be deploying Active Directory into your Virtual Network, you cannot use Azure DNS and will need to provide details for your AD DNS. The first step is to create the Azure Virtual Network and Microsoft have a good tutorial explaining it here. Create Azure Virtual Network and Start Gateway Hopefully this post will save others a lot of time.

TMG 2010 does support these requirements but getting full connectivity working has proven to be harder than expected. VPN device must fragment packets before encapsulating with the VPN headers.VPN device must support AES 128-bit encryption function, SHA-1 hashing function, and Diffie-Hellman Perfect Forward Secrecy in “Group 2” mode.Establish IPsec Security Associations in Tunnel mode.VPN device must have a public facing IPv4 address.The VPN Devices for Virtual Network page explains that other devices may work as long as they support the following:

This is still a preview release and Microsoft currently only support specific Cisco and Juniper devices that have been tested. The Azure VMs then act like a branch network with full connectivity and you can add Domain Controllers in the Azure Virtual Network. What this allows is persistent Virtual Machines (which retain the same private addresses) running in Azure that can be joined to your on-premise Active Directory using a site-to-site IPsec VPN.
