Ubuntu – dnsmasq and mac filter

If you're trying to run DHCP on them, which don't eth1 and eth2 have static addresses? I assume you're trying to isolate the wireless network from the wired LAN (otherwise you'll need bridging)?

You can do this by specifying only a static range

dhcp-range=192.168.0.0,static

EDIT: Change the address range above to meet your requirements.

With no dynamic ranges specified dnsmask will only provide addresses to hosts that have a corresponding dhcp-host configuration

# Specify a subnet which can't be used for dynamic address allocation,
# is available for hosts with matching --dhcp-host lines. Note that
# dhcp-host declarations will be ignored unless there is a dhcp-range
# of some type for the subnet in question.
# In this case the netmask is implied (it comes from the network
# configuration on the machine running dnsmasq) it is possible to give
# an explicit netmask instead.
#dhcp-range=192.168.0.0,static
