Purposefully messing up tcp/ip handshake

So I’ve been trying to find a way to mess with the obvious intrusion attempts to some servers I’m running. Most obvious are requests to “/wp-admin”, and the like. I don’t run WP but would like to mess with them by either leaving them hanging or maybe allowing them in to some weird honeypot/fake site? Anyone got ideas or ways to purposefully screw up the tcp handshake or the like?
