In Lock Mode, the Lock is acting as a combined router / firewall on the network. With its factory default settings, the Lock is connected to the Internet via its WAN port or a 4G modem. In this mode, the Lock creates its own protected local network for the connected devices. In this configuration, only devices that are connected to the Lock by cable or via WLAN access point are accessible with the Key.
In Client Mode, the Lock is not acting as a router / firewall on the network, it’s acting as a client. This means the Lock will provide a secure remote access to the network but can not protect the devices connected to the same LAN, as the default gateway to Internet is another device on the network.
Client Mode can be used for connecting the Lock to an existing network (e.g. an office network). In this mode, the Lock joins the network like any other device (e.g. a PC) and provides remote users with access to other devices in the same network.
In Client Mode, the Lock can be considered to function like a network switch, not routing traffic between the WAN and LAN but switching only between LAN ports. WAN port should not be used in Client mode. The Lock must be connected to Internet via any of the LAN ports and either fixed IP address or DHCP Client to be configured on the Lock.
