I likewise wonder from time to time whether I should replace WireGuard's allowedips.c trie with something better: https://git.kernel.org/pub/scm/linux/kernel/gi

  I use Wireguard rarely enough that the AllowedIPs concept gets me every time. It gets easier when I replace it mentally with “Route=” :-)

    It's like a routing table on the way out and an ACL on the way in. Maybe an easier way to think of it.

      Sure, but how does this differ from a routing table with RPF (which is default in Linux already)?

        It's associated per-peer, so it assures a cryptographic mapping between src ip and public key.
