| − | = AWS Networking =
| |
| − | | |
| − | * VPCs, subnets
| |
| − | * Default dynamic public IP
| |
| − | * Default static private network/IP
| |
| − | * Reserving a static public IP under "Elastic IPs", cost of doing that
| |
| − | * VPC dashboard:
| |
| − | ** https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html
| |
| − | ** New VPC vpc-ops345 with CIDR block 10.3.45.0/24, no IPv6
| |
| − | ** Subnets: create a new one in vpc-ops345 named subnet-ops345, in us-east-1a, 10.3.45.0/24 (to fit inside the VPC)
| |
| − | ** Edit subnet, enable auto-assign public IPv4 addresses
| |
| − | ** Internet Gateway: Create ops345-internet-gateway, attach to vpc-ops345
| |
| − | ** Create new Route table ops345-route-table, add route for 0.0.0.0/0 through ops345-internet-gateway. Then add explicit subnet association to subnet-ops345
| |
| − | * Create a new security group "ops345sg" in vpc-ops345 with only the SSH port open.
| |
| − | * Create a new VM named "router", in the new vpc/subnet.
| |
| − | ** Follow the instructions in lab 1, except use the subnet-ops345 and ops345sg. Also create a new key called ops345-allmachines-key
| |
| − | ** Note that "Auto-assign Public IP" is enabled by default, but don't change it.
| |
| − | ** Wait till it starts, then go to "Elastic IPs" and associate elastic IP with router
