 +==== 5.6 Remote Console on VRM ====
 +
 +This feature allows full remote control of a GX Device, over the internet:
 +{{ :​vrm_portal:​vrm-remote-console-headline.png?​nolink |}}
 +
 +Remote Console on VRM is disabled by default. Activate it by following these steps:
 +
 +  - Enabling the feature in the Settings -> Remote Console menu
 +  - Either set a password; or disable the password
 +  - Restart the GX Device.
 +
 +Now, the Remote Console option will appear in the menu on the VRM Portal. Click it to open the Remote Console:
 +{{ :​vrm_portal:​vrm_remote_console.jpg?​direct }}
 +
 +Trouble shooting tips:
 +
 +  - Make sure that basic communication with VRM works, see chapter 5.4.
 +  - After enabling the feature, make sure to set (or disable) the password.
 +  - Also make sure to restart the CCGX.
 +  - Make sure to update the CCGX to the latest firmware version. The last stability improvement for Remote Console was made in version v2.30.
 +  - After the restart, check the Remote Console on VRM status shows online or a port number. In case it says offline, or port number 0, the CCGX was unable to connect to the Remote Console server. This is normally caused by a (company) firewall, blocking the connection. The solution is then to configure an exception rules in the firewall.
 +  - Verify that your local web browser can access the [[https://​vncrelay.victronenergy.com/​|websocket port (443 on vncrelay.victronenergy.com]]). If you click that link and get 'Error response, method not allowed',​ it means the connection between your PC and the VNC relay is working. If you get a timeout or another (browser) error, there may be a firewall blocking the connection.
 +
 +Remote Console on VRM uses the same reverse SSH tunnel as is used for Remote Support: outbound connection to supporthost.victronenergy.com on port 22, 80 or 443. It is not necessary to set up port forwarding in routers to use Remote Console on VRM. It is necessary for the firewall/​router to which the CCGX is connected, to allow outbound connections to supporthost.victronenergy.com on at least one of the three mentioned port numbers. Most routers will allow this by default.
