Hi all,

My remote network is a different one: 10.41.94.240/28, just in case :)

Should I add the remote network or subnet to my existing network in
undercloud? Or new subnet, which is configured on remote site?
if yes,
  how to specify, that A host should be used on the A network, and B host
on the B network.
  how to add it?
fi

I believe FW is all to all. But at this stage, my main concern is that I do
not get any info into log in dnsmasq.log

Any thoughts?
