Ok, here's an issue where I might have some issues with understanding
how this actually works.
I have a machine that has both a public IP on eth0 and a private one on
wlan0.
I tried to block off all inbound traffic on eth0 with
ufw deny in on eth0

Instead I now seem to have blocked all incoming traffic, including the
wlan0 interface (which kicked me out of the ssh session).
What am I doing wrong here?

ah, no, turns out it just blocks everything and I needed to allow port
22 first. yeah, I was thinking the wrong direction.
