You may already have Resource Groups and Virtual Networks setup, if so you can skip the first few steps. Note: You could вЂhairpinвЂ™ multiple sites over this one tunnel, but thatвЂ™s not ideal.Д¬onfigure Azure for вЂRoute BasedвЂ™ IPSec Site to Site VPN 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, вЂњIf traffic is destined for remote network (x) then send the traffic вЂencryptedвЂ™ to local security gateway (y).вЂќ 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 itвЂ™s the same as вЂњIf traffic matches the interesting traffic ACL, then send the traffic вЂencryptedвЂ™ to the IP address specified in the crypto mapвЂќ.

Can be used for VPNs to multiple sites.

Cisco ASA now supports Virtual Tunnels Interfaces (After version 9.7(1)). These were typically used with routers, because routers used 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).

This article will deal with Route Based, for the older Policy Based option, see the following link With VPNвЂ™s into Azure you connect to a Virtual Network Gateway, of which there are TWO types Policy Based, and Route Based. This coversВ the, (more modern) Route based VPN to a Cisco ASA thatвЂ™s using a VTI (Virtual Tunnel Interface).
