Hi,
I was just wondering whether the --interface and --except-interface
options to dnsmasq would also apply to messages like DHCPDISCOVER and
DHCPREQUEST which are broadcast to 255.255.255.255.
In my particular case I have an existing dnsmasq instance that is
running, and I want to add a second dnsmasq instance to handle DHCP
requests coming from a specific subset of interfaces. I don't want the
primary dnsmasq instance to see the requests coming in on those
interfaces, and I don't want the second dnsmasq instance to see requests
coming in on the other interfaces.
As a concrete example, suppose I have network interfaces eth0/eth1/eth2
and I have instance A of dnsmasq which is run as "dnsmasq
--except-interface eth2", and instance B of dnsmasq which is run as
"dnsmasq --interface eth2 --except-interface lo".
If a broadcast DHCPDISCOVER or DHCPREQUEST comes in on eth0/eth1 which
dnsmasq instance(s) will see it?
If a broadcast DHCPDISCOVER or DHCPREQUEST comes in on eth2 which
dnsmasq instance(s) will see it?
If a broadcast DHCPDISCOVER or DHCPREQUEST is emitted by an entity on
the local host which dnsmasq instance(s) will see it?
Thanks,
Chris Friesen
