  • issue with ufw blocking interface

    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.
