I was using GUI interface to attached router to external network and i did used Network > Router > Interface > Add-interface menu
where it asked me for Subnet and Fix IP (option) and i thought it will allocate IP from pool but it picked gateway IP and screwed my network :( It would be good if horizon review details before save it, currently GUI just save it configuration without showing any detail what its going to do.
