fck-nat is a ready-to-use AWS EC2 AMI (ARM and x86, built on Amazon Linux 2023) that turns a cheap instance like a t4g.nano into a NAT instance, replacing costly AWS Managed NAT Gateways. It includes Terraform/HCL deployment tooling and supports up to 5Gbps burst NAT traffic with optional high-availability mode.
Use cases
- replace expensive AWS managed NAT gateway with a cheaper NAT instance
- deploy a NAT instance AMI with up-to-date security patches
- reuse bastion hosts as NAT instances
- cut VPC egress networking costs on AWS
- set up NAT for private subnets in a VPC with Terraform
When to choose
- you're overpaying for AWS Managed NAT Gateways and need under 5Gbps of egress bandwidth
- you want a maintained, patched alternative to the EOL official AWS NAT Instance AMI
- cost savings matter more than a fully managed five-9s service
When to avoid
- your workload requires more than 5Gbps of internet egress bandwidth
- you need fully managed five-9s availability and can't tolerate rare instance outages
- you prefer not to operate non-managed services
