JuJu Guiから
nova-cloud-controller で console-proxy-ip をグローバルのアドレスに変更（hogehoge.comなど）

今回は、下記に変更
100.100.100.250

@maasvm-dev:~$ nova get-vnc-console 4334cf29-a393-4ac5-baa0-f9fb49df6da8 novnc
+-------+-----------------------------------------------------------------------------------------------+
| Type  | Url                                                                                           |
+-------+-----------------------------------------------------------------------------------------------+
| novnc | https://192.168.0.200:6080/vnc_auto.html?path=%3Ftoken%3Dadd8b447-9751-4b50-8f95-5cb92dd60f57 |
+-------+-----------------------------------------------------------------------------------------------+

Change console-proxy-ip local => 100.100.100.250.250

@maasvm-dev:~$ nova get-vnc-console 4334cf29-a393-4ac5-baa0-f9fb49df6da8 novnc
+-------+-------------------------------------------------------------------------------------------------+
| Type  | Url                                                                                             |

下記のようにつなげてあげる
100.100.100.250:6080 → 192.168.0.200:6080
