It isn't listening to all NICS - the '--listen-address 192.168.122.1'
parameter causes it to only listen on the NIC with the matching IPv4
address. You can confirm this with 'netstat -t -l -n -p | grep dnsmasq'

# netstat -t -l -n -p | grep dnsmasq
tcp        0      0 192.168.122.1:53            0.0.0.0:*                   LISTEN      2327/dnsmasq

Daniel
