Docker: Telnet from container to host machine?

Question

linux

Hello!
Os Ubuntu
The entire local server is deployed via docker-compose.
I'm trying to set up xdebug on my work computer.
Did according to the instructions - https://blog.denisbondar.com/post/phpstorm_docker_...
The problem is that the xdebug outgoing connection does not reach the host machine.
Docker version - 18
Through ifconfig - ip address of the host machine 192.168.220.1
If I puff from the container:
telnet 192.168.220.1 9000
Then the connection falls off by timeout.
Everything is ok on my home laptop. True version of docker is 17.
Has anyone encountered a similar problem?

Answer 1

At work, according to the rules of the network, the ports were closed.
Something like this :)
Check the port.
