I was recently playing around with DNSSEC and figured out that the root DNS zone . uses NSEC and not NSEC3 to prove the absence of a resource record. This looked interesting to me and triggered some ideas. So I did some experiments and here are the results.
WireGuard is a relatively new open-source software for creating VPN tunnels on the IP layer using state of the art cryptography. I attended a self-organized session by the creator and developer Jason Donenfeld at the 34c3 who explained how WireGuard works and how it can be used. I was quite impressed by it’s simplicity and gave it a try. It worked more or less out of the box. Now I created a more advanced setup for accessing my home network.
In this blog post, I will describe how you can use it to remotely access your home or corporate network from any external network as a so-called road warrior.
