Let me explain this, in the previous post, we launched an EC2 instance in public subnet and we already have configured an Internet Gateway for VPC and configured route in route table to allow incoming traffic. In this post, we will setup a Bastian server in our public subnet (so internet traffic is possible).įirst we will connect to this Bastian server, from there, we can then connect to private EC2 instance (remember the rule in security group, we configured, in previous post, we allowed traffic from within our VPC to port 22 on the private EC2 instance). Once remote connectivity has been established with the bastion host, it then acts as a ‘ jump– server’, allowing you to use SSH or RDP to login to other instances (within private subnets) deeper within your network. The purpose of bastian host is to restrict the access to a private network from an external network. Bastian Hostīastion servers are instances that sit within your public subnet and are typically accessed using SSH or RDP. This is where we can use a Bastian Server. Our instance has no public IP, it is in Private Subnet (no direct route from internet). Now, if we want to SSH into EC2 instance on private subnet from our home/office (or using development machine), currently we can’t. Here is how our architecture is currently setup, for the reference: We will learn why we need those and some of the options available to us. In this post, we will continue and setup Bastian Host and NAT instance in our VPC. With security groups configured, we were able to SSH to EC2 in public subnet. One in public subnet and one is private subnet. ID element _(Rarely used, not included by default)_.In previous post on AWS Elastic Compute Cloud (EC2) Basics, we launched two EC2 instances.
