Meanwhile that has been tried by original poster.

This email is an invite to report back how that it did go.

A "Yes, multiple shared-networks are allowed by the config
checker and it works as expected" will do.


Upon "doesn't work" is more effort expected, like reporting how it fails
and what was the hoped outcome. Because that is information that helps
making dnsmasq possible better.

I'm aware that https://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2022q4/016667.html
screams nasty stuff like

 * Unawareness of discsussion order
 * Unawareness of line wrap behaviour of email client program
 * Hope that insults get unnoticed
