Being pedantic, because there's all sorts of reasons a TCP connection works in the face of buggered routing, not the least of which is that the endpoints are on the same L3 network. Yeah, guest networks are a thing, but a postit note with the WLAN PW is an even bigger thing if most of the home networks I'm familiar with are any indication. Bottom line is that nothing on an IP network should do something st00pid if it gets a random weird packet from a random IP, because the whole history of IP shows that you will, eventually, get one.
