We can configure the policies in the security group and control how the traffic flows through the AWS cloud. You can think of a security group as a stateful firewall, though it’s not a firewall. I have also deployed the Amazon EC2 Linux AMI image in the private subnet. We also added a management subnet in the subnet associations in the public route table.
The only difference is that in that instead of using the subnet 10.100.0.0/16 we have used 10.200.0.0/16, with only one octet difference.Īpart from that private and public subnet, we need to configure management subnet 10.200.17.0/24 mapped to the public route table. We have already covered the creation of private and public subnets over here, and you may follow the step-by-step guide to proceed with the subnet configuration. And it is expected to incur costs doing this lab. After the deployment, the private host can talk to the internet through the ASA firewall.īefore you begin, You need to have an AWS account. We will build a Cisco ASAv where the inside interface is connected to the private subnet and the outside interface is connected to the public subnet. We have an EC2 instance running in the private subnet at the moment, it can only talk to the other hosts in the private subnet, not to the internet. We have a VPC with the subnet 10.200.0.0/16, which is split into different subnets, such as Private, Public, and management. Below is the topology that we are going to use. There are different ways we can architect or design the network. Since it is virtualized instance, it is called ASAv or vASA.

We will install the ASA firewall in the AWS EC2 cloud in this blog post. You may check them out if you are interested.

We have looked at how to set up IPsec VPN on ASA to different vendors in our blog post. If any 3 rd party users wanted to connect to your network, you could build an IPsec tunnel to extend the network easily. So users can connect to the VPN remotely. You can also take advantage of this setup and configure end-user VPNs such as Any connect. Many users are now using the ASAv on the AWS cloud it sits at the edge of the cloud network protecting your AWS resources. Asa is one of the popular firewall offerings from cisco, used by many on-prem enterprise networks.
