Metaphor Gateway is a high-performance eBPF NAT gateway for AWS that replaces AWS NAT Gateway at a fraction of the cost. Kernel-level packet processing, multi-Gbps throughput (often under 1% CPU overhead), includes a real-time traffic monitoring dashboard, and supports optional Cloudflare Connector tunnel integration for Zero Trust integrated egress and VPN routing options.
Overview
Metaphor Gateway is a next-generation NAT gateway purpose-built for AWS, using eBPF technology to process network traffic directly in the Linux kernel. Where AWS NAT Gateway charges hourly plus data processed, Metaphor Gateway runs on your own EC2 instances - delivering significant throughput with sub-millisecond latency, often under 1% CPU overhead.
Metaphor Gateway integrates natively with AWS Gateway Load Balancer (GWLB) via GENEVE encapsulation, enabling transparent insertion into your VPC traffic flow with automatic scaling and high availability. The included Scry dashboard gives you real-time visibility into every connection traversing your NAT - fleet health status, TCP state distribution, per-connection byte counters, top talkers, and critical event alerts. No more flying blind through your NAT layer.
For organizations that need secure egress, Metaphor Gateway supports optional Cloudflare Connector tunnel integration, routing user traffic through Cloudflare's global network for security filtering, while keeping health check traffic on the direct path. Deployment is simple via CloudFormation.
Highlights
- Replace AWS NAT Gateway and cut costs by up to 90%. Metaphor Gateway processes multi-Gbps on a t4g.medium, often with under 1% CPU overhead. A single instance, or multi-az deployment replaces AWS NAT Gateways, eliminating per-hour and per-GB data processing charges while giving you full control over your NAT infrastructure.
- Real-time traffic monitoring dashboard included. The Scry dashboard shows fleet health, live connection tracking, TCP state distribution, top talkers, and critical alerts. Giving you complete visibility into your NAT layer that AWS NAT Gateway simply doesn't provide.
- Simple deployment with GWLB integration and optional Cloudflare Zero Trust filtering and networking. Deploy via CloudFormation with native Gateway Load Balancer support, automatic GENEVE encapsulation, and VNI detection. Add Cloudflare Connector tunnel integration for secure egress with advanced networking options.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
