SSH port configuration
Default port for SSH is 22. It is recommended to change this to something less
common to increase system security. Changing SSH port on M2M Gateway is
done by entering new port to a configuration field located in the bottom of the
SSH-VPN configuration screen and pressing Change port button.
Note!
Changing the SSH port on M2M Gateway requires configuration changes to
SSH-VPN connected Arctics as well. Also remote SSH access has to use new
port.
