Define better network driver than "host"

[obzocker]

Is your feature request related to a problem? Please describe. Currently the readme.md defines a example docker-compose with the docker network driver "host". Without looking in the code it seems that this programm does not need the complete access to all ports/network.

It would be much better from a security standpoint to define the exact ports which need to be open to minimize the attack vector

Describe the solution you'd like Update the readme to concretely specify the ports which needs to be open and update the docker network driver.

THe programm does not need any ports forwarded but to get the host network is needed for the IPv6 as it is explained right under the docker-compose
