CLOUDFORMATION​

DEPLOYMENT ESSENTIALS​

For effective functioning, the DiscrimiNAT Firewall will need:

  1. A machine type with at least 2 vCPU and 2 GiB RAM. A t3.small should suffice where throughput requirements are basic and allowlists small. Otherwise a c6a.large (or c6i.large) makes a good choice for constant throughput. Talk to our DevSecOps to get the sizing right!
  2. An IAM policy that can read some EC2 metadata, write logs and set instance health (of itself). See the IAM Instance Profile page for details.
  3. Ability to forward IP packets with the SourceDestCheck property of the network interface turned off.
  4. A public IP with routing to the Internet via the AWS supplied Internet Gateway.
