I also use dnsmasq. I also use it to give DHCP addresses to the clients
on my home network. If find this feature very useful since all I need to
do is to give hostname to a computer and make it a DHCP client. The
dnsmasq server, in which I specify which hostname (with mac address)
should ge what IP addresses, then gives the relevant IP address to that
computer. Very neat and easy.
The computer that runs dnsmasq is connected to my ADSL modem. That
computer makes the pppoe connection and my modem works in a bridge mode.
So basically the modem is out of the picture for anything other than the
internet connection.
