How to change network settings as non root user

Hello,

I’m trying to create a service and run it as non root user.
Actually it did not fully work. I guess that additional permissions to reconfigure some networks settings (i.e. proxying) are required.
But how to do that. Add the user to an additional group?
Is there a special group to handle network settings?

maybe you can give way more information. Which network settings you like to change. Best is to give very detailed examples.
