How to Set Up a Linux Server as a Router with nftables

In this episode, Lucas and Luna dive into turning a Linux server into a high-performance router using nftables. They explain the core concepts of packet filtering, network address translation, and routing, then walk through a practical setup with a simple dual-NIC configuration. You'll learn how to configure nftables to forward traffic, set up NAT for internet sharing, and secure the router with basic firewall rules. They also discuss performance tuning tips, such as enabling IP forwarding and tweaking sysctl parameters, and touch on troubleshooting common issues. Whether you're building a home router or a small office gateway, this episode gives you the concrete steps and mental models to get it right. No prior nftables experience needed, but basic Linux command-line comfort is assumed.
