Little Snitch Block Port
Sep 07, 2011 I told the AppleCare guy, I'd call back if I couldn't figure it out, but I doubt they'll help me work through a Little Snitch issue. I know Software Update tries to connect via port 80, but so do tons of other apps. I can't find anything that's blocking anything through system preferences. I can't figure it out. Can anyone help. May 01, 2017 Little Snitch is a traditional software firewall for macOS. You can use it to monitor applications, preventing or permitting them to connect to attached networks through advanced rules. OpenSnitch is a GNU/Linux port of the Little Snitch application firewall written in Python.
Starting with macOS 10.15.4 the above “Legacy System Extension” message will be shown when Little Snitch is installed.

I have disabled all incoming rules, and explicitly added a block for ssh. However, little snitch blocks absolutely nothing.Rules:

However, from another host on my network:
Little Snitch Block Port Jefferson
What makes it worse it that I was trusting Little Snitch to block this for some time, and I realized today I can even ssh into my machine from a machine I've connected to via an openvpn connection....so I've been exposing myself to that entire network on the other side.
Help please! Thanks in advance.
