Hi Tixy.
For the archives, the documentation to configuration of dnsmasq(1) is
in /etc/dnsmasq.conf, the dnsmasq configuration file. It is verbose,
and there are many options. Read thoroughly.
It is a very impressive accomplishment, and works well, and is fairly
easy to get working, (once familiar with the configuration file.)
As a closing note, the DHCP/DNS services, (for wlan0,) are configured
in the /etc/dnsmasq.conf file, *_NOT_* /etc/dhcpcd.conf, which is the
usual alternative.
(This is where I went astray-I mean the name is dnsmasq, probably
meaning it is something to do with dns, duh.)
Thanks to all,
John
