Thank you, that is interesting information: I never used it.

> Mainly. Section [Networking] optional Route
Do you mean [Network] section?
And Route is a section, right? (I see also a Route parameter and that's
about IPv6)

I wonder if that's comparable to what I was trying to do with the DNS proxy
in front of samba's DNS.

write it out atm. (sorry)

Don't worry, you already gave me a good starting point.
