That being said, I still don't see any reason for doing something in WG for which (a) there's no threat model, (b) a perfectly adequate and well-tested solution already exists, no matter whether the implementation is userspace, kernelspace, or inside a network card's firmware (well …). Yes, ssh has a config option for that, but ssh runs on systems without kernel-level IP filters. Using WG on a machine that will forward IP packets but cannot do any firewalling is not a credible use case. -- -- Matthias Urlichs
