OpenBSD makes a great router. It's simplicity and ease of configuration makes it perfect for network infrastructure applications. Everything you need to build a network of any size is built into the base system, plus its man pages and examples cover everything you'd need to know. While I've been an OpenBSD user for years, I'm finally in the process of replacing the router provided by my ISP with a PC Engines APU2E4 running OpenBSD.
