configuration or opening up of firewalls in almost all situations. The 0.1% of situations where it doesn't
work out of the box are, for example, large corporate networks with special security, or long range
expensive satellite or radio supported networks, such as seen in rural areas of Africa and other
remote areas.
When Remote Console on VRM is enabled, the GX Device will open and maintain a connection to any
of the servers pointed to by supporthosts.victronenergy.com. Which currently resolves to two IP
addresses (84.22.107.120 and 84.22.108.49), and likely more in the future. The technology used is
ssh, and it will try to connect using port 22, 80 and 443, only one of them needs to work. The reason
for it to try all three is that on most networks one of them will be allowed by the local firewall.
Once connected to one of the supporthost servers, that reverse ssh tunnel is waiting to be connected
from someone needing the connection. Which can be your browser, or a Victron engineer since this
same technology is used for the Remote Support functionality; for more information see above.
When using Remote Console on VRM, the browser will connect to either vncrelay.victronenergy.com,
or vncrelay2.victronenergy.com, using websockets on port 443.

A Glass Bridge is a MFD (Multi-Functional Display) that integrates a boat's systems and navigation
status into a large screen or screens at the helm of the vessel, so doing away with multiple gauges,
brackets and wiring complications.
A Victron system can be easily integrated into that, as shown in this video:
