Thanks for the info.

Right now I'm trying to find out how to run multiple dnsmasq instances 
for different interfaces on Debian with systemd.
The second interface shall be a virtual one on the real one with a 
different ip address, so that I can distribute "a different DNS server" 
to my test client.

Thanks for your time
