Security groups

Security groups act as virtual firewalls that control inbound and outbound traffic to your instances. Our 3 nodes will need to open up connection ports for SSH access, and for each of the 4 network layers to communicate over.

Create a Security Group​

First, navigate to the Security Groups section in the Amazon EC2 console.

Menu ec2

Click on Create Security Group​

Create a new security group and provide a name, for example MetagraphSecurityGroup.

Add Inbound Rules​

Inbound rules define which ports accept inbound connections on your node. We will need to open up ports for SSH access and for each of the metagraph layers.

Click Add Rule under the Inbound Rules section and add the following rules:

Type	Protocol	Port Range	Source	Purpose
SSH	TCP	22	0.0.0.0/0	SSH access
Custom TCP	TCP	9000-9002	0.0.0.0/0	gL0 layer
Custom TCP	TCP	9100-9102	0.0.0.0/0	mL0 layer
Custom TCP	TCP	9200-9202	0.0.0.0/0	cL1 layer
Custom TCP	TCP	9300-9302	0.0.0.0/0	dL1 layer
