I try to connect to my Raspberry Pi from my Mac via an ethernet cable. I get: ssh: connect to host 169.254.32.96 port 22: Connection refused.

Nmap says this:

Starting Nmap 7.12 ( https://nmap.org ) at 2016-11-09 10:43 CET
Nmap scan report for 169.254.32.96
Host is up (0.00088s latency).
Not shown: 749 closed ports, 250 filtered ports
PORT   STATE SERVICE
80/tcp open  http

When I connect to my Raspberry via WLAN and the Raspberry is connected to my Airport Express then connection via SSH is possible.

Nmap for this case:

Starting Nmap 7.12 ( https://nmap.org ) at 2016-11-09 10:44 CET
Nmap scan report for 10.0.1.12
Host is up (0.0015s latency).
Not shown: 995 closed ports
PORT     STATE SERVICE
22/tcp   open  ssh
80/tcp   open  http
5002/tcp open  rfe
5901/tcp open  vnc-1
6001/tcp open  X11:1

I must connect to the Raspberry via ethernet cable for a show case. What do I have to change? I changed the iptable policies already but it didnt work. And I dont know which rules are used first. Additionally, I installed Eclipse Kura, tightvncserver and OpenXC framework. Since I installed those, I got the problems and entries to the iptable I don`t want to have. When I try to flush my iptables the Raspberry is operating at full capacity and unreachable.

Thanks for your help!

Connection refused means just what it says. You seem to think this has something to do with IP routing, which it does NOT - you would get a not found (or similar message) if this was so.

The most likely cause is ssh security settings on your Mac.

I enabled ssh on my pi using sudo raspi-config and then followed this: https://mycyberuniverse.com/mac-os/connect-to-raspberry-pi-from-a-mac-using-ethernet.html

Worked a charm.
