Discussion on: Access host from a docker container

Been a while so I'm hazy. From memory my docker containers were running on 192.168.0.0/24 while my LAN is on 192.168.1.0/24. I just needed to tell ufw to allow access to that port from 192.168.0.0/24

I had exactly the same problem.
Confusingly ping was working from the container but e.g. wget and traceroute etc. were not (a good indication of a firewall "problem").

In my set-up the solution was:

ufw allow in to 172.17.0.0/16 proto tcp port 8084

where 172.17.0.1 is the docker0 IP address and 8084 the port on the host machine.
