See below for the results of various commands. Prefix xx.xx is the
Ethernet network while yy.yy is the wireless network. Both of them are
in the public IP range (in case it matters). I also added the result of
the dig command, without and with specifying a DNS server. Notice that
directly querying the xx.xx server works, while querying dnsmask or an
yy.yy server fails in the same way. I haven't put the tests in this
message, but as you can guess, if I unplug eth0, both dnsmask and yy.yy
server succeeds, and if I kill wlan0, both dnsmask and xx.xx server
succeeds.

$ ip route
default via xx.xx.212.190 dev eth0  proto static 
yy.yy.72.0/24 dev wlan0  proto kernel  scope link  src yy.yy.72.155  metric 2

xx.xx.212.128/25 dev eth0  proto kernel  scope link  src xx.xx.212.250  metric
