I've upgraded my M9 plus v2 to the 1.5.0 firmware last week. The web interface is now accessible without needing to specify the port number, ie it now runs on the default http port of 80. Before I think it used 30000. In fact, you can also use https if you wish (however your browser will likely compolain about the certificate).
If your LAN IP in advanced settings is 192.168.1.1 then use http://192.168.1.1
