Jetson Nano Jetpack 4.2 firewall broken - possible kernel compilation issue missing iptables modules

Thank you, a broken firewall seems to be a very critical security issue to me - I am surprised nobody else noticed this.

I think most embedded developers are focused primarily on getting something out the door with security as an afterthought. I am surprised but not suprised nobody bothered to try a ufw enable. Thank you looking into this and thank you for caring about security.
