With Debian 10 (buster) the default firewall is nftables so it’s time to convert my iptables rules. Since Debian stable is never first with anything I was surprised to see how relative few articles and blogs there are about nftables compered to iptables.
I have been watching the WireGuard project with interest for a couple of years. I like how WireGuard is constructed. A small code base that focus on the core functionality. The use of standard Linux networking tools and simple public/private keys.
