Oh yes ok this does help a bit. I found a thread in the dnsmasq archives
demonstrating how simple defining a seperate pool is in dnsmasq as well.
However I could still find no working examples on how to configure that
pool to distribute a DIFFERENT gateway than the first pool recieves. It
seems to me that the trick might be in 'labeling' the two subnets.
Something like the following:




Note the set:lan1 and set:lan2. And then perhaps later on in the same
configuration something like the following:


But still.. Just blindly attempting this is to see if it works is
something I call the 'dart board method' throwing random commands or
configuration statements at my daemons or utilities in desperate hope
they will begin doing what I wish them to do. Because this is such an
important project, I would still feel very relieved if someone could
demonstrate for me exactly how this might look when done correctly.

Thank you again for all your help,
