This setting governs the incoming data traffic, i.e. the following settings only apply to data traffic arriving from
outside the network.
Sample setting
The following rule applies according to the device type:
If the connection is established to the Internet via WAN (external router, fixed line), the WAN Ethernet port is
the gateway to the Internet. Thus, the firewall controls the traffic from the WAN Ethernet to the LAN Ethernet.
If the connection is established to the Internet via Modem, the Modem is the gateway to the Internet. Thus, the
firewall controls the traffic from the Modem to the LAN Ethernet.
