Expected behavior
Run an UDP listener inside of a container with port map 8125:8125/udp.
(I am using “socat UDP-LISTEN:8125,fork -” for the listener. See dockerfile below.)
Send data to UDP port 8125 on the host, socat receives it and prints it.
(I am “date | nc -u 8125” to send data.)
Actual behavior
works: date | nc -u 127.0.0.1 8125
works: date | nc -u localhost 8125
works: date | nc -u ::1 8125
does not work: date | nc -u $(ipconfig getifaddr en0) 8125
(the IP of en0 is 192.168.27.107, see ifconfig output below)

Steps to reproduce the behavior
- run socat in container, with udp port mapped
- send data to that udp port
