Mmm, I hoped that 'What has already been tried?' got an answer like
Configured for daemon A ...., for daemon B ....
Configured for daemon A ...., for daemon B ....
Configured for daemon A ...., for daemon B ....
Configured for daemon A ...., for daemon B ....
Repeated that with starting the other one first

Acknowledge on "these 5 networks". What about telling the IP-adresses on
the interfaces of the box where the tests^Wconfiguration attempts are done?
(I'm lost, previously one computer with eth0 and eth1, now five networks
and nothing about eth0 nor eth1.)
For what it is worth: Over here is it "dnsmasq works" My reason for
involvement in discussion like this is "can dnsmasq be better?" and/or
"what can i learn more about dnsmasq?". I aim for win-win. Making lots
of effort to understand what is going on the other side, reduces "my win".

it shows what is connected by what. (Villages by roads, Cities by
railwaytracks, computers by network equipement.)
