You can do the next two steps together, but I prefer to do then separately, or it will error if the first one does not complete! Note: This will take a while, go and put the kettle on! Make sure all running tasks and deployments are complete before continuing. You can’t change the name, (you could before, then it wouldn’t work, which was strange, but I suppose it’s fixed now) > put in another network that’s part of the Virtual-Network, but does not overlap with the subnet you created in the previous step > OK.Īll Services > Virtual Network Gateways > Create Virtual Network Gateway > Name it > Policy Based ( Note: This will change the SKU to Basic) > Create New Public IP > Give it a Name > Create.

If you are a ‘networking type’ it’s part of the virtual network, but is more specific than the subnet you already created. To further confuse all the network engineers, we now need to add another subnet, this one will be used by the ‘gateway’. OK, if you’re used to networking this can be a little confusing, we are going to create a virtual network, and in it we are going to put a virtual subnet, (yes I know this is odd, bear with me!) It’s the ‘ Subnet Name‘and ‘ address range‘ that things will actually connect to, (10.0.0.0/24).Īll Services > Virtual Networks > Create Virtual Network > Give the Virtual Network a name, a subnet, select your resource group > Then create a Subnet, give it a name and a subnet > Create.

You may already have Resource Groups and Virtual Networks setup, if so you can skip the first few steps.

Requires Cisco ASA OS 9.7(1) So no ASA 5505, 5510, 5520, 5550, 5585 firewalls can use this.Ĭonfigure Azure for ‘Policy Based’ IPSec Site to Site VPN.

Can be used for VPNs to multiple sites.

But Cisco ASA now supports Virtual Tunnels Interfaces (After version 9.7(1)) These were typically used with routers, because routers use Virtual Tunnel Interfaces to terminate VPN tunnels, that way traffic can be routed down various different tunnels based on a destination, (which can be looked up in a routing table). Note: You could ‘hairpin’ multiple sites over this one tunnel, but that’s not ideal.

Can only be used for ONE connection from your Azure Subnet to your local subnet.

Can be used with Cisco ASA OS (pre 8.4) IKEv1 only,.

These came first, essentially they work like this, “If traffic is destined for remote network (x) then send the traffic ‘encrypted’ to local security gateway (y).” Note: Where Local Security Gateway is a firewall at YOUR site, NOT in Azure! This is the way traditionally VPNs have been done in Cisco ASA, In Cisco Firewall speak it’s the same as “If traffic matches the interesting traffic ACL, then send the traffic ‘encrypted’ to the IP address specified in the crypto map”. Microsoft Azure ‘Route Based’ VPN to Cisco ASA Policy Based

This article will deal with Policy Based, for the more modern Route based option, see the following link With VPN’s into Azure you connect to a Virtual Network Gateway, of which there are TWO types Policy Based, and Route Based. This is the second time have had to write this article purely because the Azure UI has changed!

The one reason I prefer Cisco over Microsoft is they rarely change things, you learn how to do something and it’s learned.
