Can't connect from different docker network to published docker service

[benjaminbear]

I have tested the following: containera with networka has a webservice running at port 80, which is published to any with ufw-docker. containerb with networkb should now be able to connect to http://containera:80, like it is without ufw, but unfortunately it doesn't work. Connecting to the host with port 80 from outside works as expected.

Did I do something wrong or is there something missing?

Same issue here. In my opinion this should be easily possible since in many cases services are running on the same machine but need to talk to each other.
