Unified management for cloud, physical, and virtual devices with Cisco Defense Orchestrator (CDO). Micro-segmentation secures east-west traffic. Provides advanced protocol inspection, including voice and video. Gain consistent security policies, enforcement, and protection across your environments. Integrates with AWS Transit Gateway for scalable inter-VPC traffic. By leveraging AWS route 53, Cisco ASAv delivers scalable remote access VPN, along with site-to-site, and clientless VPN options. Ideal for remote worker and multi-tenant environments.
Blue Line: Incoming traffic using PIP (Azure NAT) -> 10.5.99.7 (outside interface on ASAv) -> NAT 10.5.2.Cisco ASAv is the virtualized version of Cisco's Adaptive Security Appliance (ASA) firewall. Green Line: Outbound traffic from the Web VM via ASAv using UDRs. Orange Line: Outbound traffic from the Web VM via system routes.

Create Outbound Dynamic NAT on the ASAv. Notice No Change is require on the Web VMs default route. Review UDR section for a closer look at route tables For Web-subnet -> Management subnet bypass ASAv with Virtual Network as the next hop. Associate nn-east-web-subnet-2-ASAv-RouteTable” to nn-east-web-subnet-2. Review Four Route Tables (Automatically Created). Also create secondary Public IP for PAT which will be mapped to the VIP on the load balancer later. Associate Outside NIC-1 interface with Public IP. Default route on ASAv out the outside interface. 
Remove Public IP from Management interface. SSH into the management interface from the Bastion Host to do basic ASAv configuration(See configuration snippets below).Deploy ASAv From Market Place (Cisco ASAv – BYOL 4 NIC).
Verify Subnets (Mgmt,Outside,Web,DMZ) are already create in the vNets are shown in the diagram above. Let’s have a plan first on how the interfaces are going to look like.Ĭisco ASAv High Level Configuration Steps This Cisco ASAv on Azure guide describes the network appliance deployment in detail. Cisco ASAv Deployment in AzureĬisco ASAv in Azure gets deployed with 4-NICs. User-Defined tables are combined to form the Effective Routing Table, the most specific route wins and ties go to the User-Defined Routing table. You can view and edit the User Defined Routing table. Note: Currently you cannot view either the Effective Routing Table or the System Routing Table. The Effective Routing Table is a combination of an existing System Routing Table and the User-Defined Routing Table. Routing in an Azure Virtual Network is determined by the Virtual Network’s Effective Routing Table. This facilitates migration to Azure, and organizations can continue to use the skills the team already has. 
These vendor appliances are available in Azure Marketplace as VM Images that you could readily deploy. Microsoft Azure supports a large ecosystem of third party network appliance vendors. Reference Architecture with Citrix VPX Load Balancer and Cisco ASAv Firewall in Microsoft Azure Reference Architecture 2. Network Virtual Appliances in Microsoft Azure – Cisco ASAv Deployment 1. In Part-1 we deployed a Citrix VPX load balancer in one-arm mode. This is Part-2 of the Network Virtual Appliances in Azure : Cisco ASAv.
