[bennetluedersen]

Behaviour

Can't change DNS listen port

Steps to reproduce this issue

1. Use UnRaid
2. Get the container through Community Applications
3. In the settings for the container set the DNS listen port to any port other than 5053

Expected behaviour

The container should change its DNS listen port accordingly to the port set in the configuration.

Actual behaviour

The container always uses port 5053.

port to any port other than 5053

You can already map port 5053 in the container to any port on the Docker host with -p 53:5053.
