ZIA protection against Slipstream attack

I’ve become aware of the Slipstream attack. For those that aren’t aware, Slipstream is a clever attack on TCP connections that come through a NAT router (e.g. what we all have at home). It’s worth a read. (edited to add this link to the originator’s explanation - https://samy.pl/slipstream/ )

Anyhow, I’m curious about whether Zscaler has a statement around it with ZIA, and whether there’s specific licensing or config needed to provide protection.
