Scroll Down and add the subsets 10.0.2.0 and 10.0.3.0. Select ‘Subnet groups’ on the left, then ‘Create DB Subnet Group’ at the top. Now let’s just create a subnet group that can be used during our RDS setup. So we are only allowing MySQL traffic in from our public subnet. Notice the source below points to our Public Subnet. This will allow connections only from our public subnet, and not the outside world. Now let’s create a security group for our RDS server. In a production environment, if other individuals needed access to the MySQL DB, we would add rules for their machines. SSH and MYSQL traffic will only be allowed from our machines. We are basically allowing all HTTP(s) traffic from outside our VPC to the machine we will attach to this security group. Where the IPs are blacked out, use the IP to your machine. Populate the rest of the inbound rules like the following. Note: You will still need credentials, this just allows access to the port. This will allow SSH access to port 22 on the EC2 instance associated with this security group from your machine. For Source type in the IP address to your machine. Optionally you can just type 22 into Port Range. Use the drop down menu under ‘Type’ and select SSH. Select ‘MyWebDMZ’, select the tab below ‘Inbound Rules’, click add another rule. Select the VPC you just created in the bottom drop down box. Since this will be used for Bastion servers and proxy servers. Click ‘Create Security Group’ at the top of the screen. We will allow MySQL traffic, so applications can connect to our HA proxy and that MySQL traffic can be forwarded to our private subnet.Ĭlick ‘Security Groups’ on the menu to the left. We will allow HTTP and HTTPS, so we can download and install software from the internet. Here we will allow SSH traffic, so we can access this server. Let’s create a security groups for our bastion host. Nothing to do here, just pointing this out. Notice a Network ACL is already create for us. Now Check the box next to 10.0.1.0 – us-east1a’ or what ever your public subnet is named. Now we need to attach this our public subnet to this route table. This is useful for software installs and such. This route table allows traffic out to any internet address. Click ‘Edit’ and add 2 rules.Ġ.0.0.0/0 with the target being your Internet Gateway. Give this route table a meaningful name.Ĭlick the ‘Routes’ tab in the bottom pain. Select ‘Route Tables’ on the left hand side. You will notice you have a route table created by default. This route table will be used for our public subnet to give it a route out to the internet. Select ‘Internet Gateway’ from the left-hand side. This will give access out to the internet. Enter the following information, and click ‘Create’.Ĭreate an internet gateway. Select our subnet, click ‘Actions->Modify auto-assign IP settings’. Now since this is going to be our public subnet, let’s have it automatically assign public IPs to instances created here. Enter CIDR block range ‘10.0.1.0/24’ and availability zone ‘us-east1’. This was how I learned it from and it has stuck with me. I use the CIDR block range, and availability zone in my name ‘10.0.1.0 – us-east1a’. Servers in our public subnet will have public IP addresses, and access to the outside internet. Click ‘Yes, Create’ when done.įirst we will create our Public Subnet. I also select ‘Amazon provided IPv6 CIDR block’ to give more options later on. I use ‘10.0.0.0/16’, which will give me the most IPs available. This would create a lot of components for us and not be as fun.Įnter a name tag, I’ll call mine ‘MyRDSvpc. Note: If you select ‘Create VPC’ here, it will launch the VPC wizard. This will take you to view your current VPCs available. This will bring you to the VPC dashboard. From the AWS dashboard search or navigate to VPC.
