Networking is hard. No, seriously. When I started working on Nova over a year ago, my networking skills were good enough to configure a home router. I understood basic packet structure. I once used some libpcap-based packet sniffing tool and manually decoded the authentication packets that a game was using. A year of bridging, routes, vlans, tap devices, vpns, and tcpdumping later, and I've rewritten the networking code in Nova at least three times. I understand a lot more now. And I still feel like a n00b.
