Summary
This is your go-to when you're wrestling with iptables rules, setting up policy-based routing, or debugging why packets are disappearing into the void. It covers the full stack from nftables syntax and NAT chains to network namespaces and systemd-resolved quirks. The guidance is production-focused, with specific commands like using ss over netstat and tcpdump filters for actual troubleshooting. What I appreciate is the emphasis on documentation and the blunt warnings about flushing firewall rules remotely. If you're doing anything beyond basic DHCP configuration on Linux, you'll reference this repeatedly.
