The Ethernet interfaces on any publicly accessible device can potentially be used by unauthorized persons to gain physical access to a network. The Ethernet interfaces on the device can be disabled to prevent this.
LANconfig:
- Interface usage
- Here you select how this interface is to be used.
Possible values:
- None (power down)
- The interface is deactivated.
- Idle
- The interface is not allocated to any particular task, but it remains physically active.
- LAN-1 to LAN-n
- The interface is allocated to a logical LAN.
- DSL-1 to DSL-n
- The interface is allocated to a DSL interface.
- DSLoL
- IPv4 addresses can only be masked ("NAT") on WAN connections. If you want to masquerade in the direction of a LAN or WLAN interface, then the corresponding LAN or WLAN interface must be declared as a DSL port in order for it to establish a WAN connection (typically by IPoE or DHCPoE ).
- Monitor
- The port is a monitor port, i.e. everything received at the other ports is output via this port. A packet sniffer such as Wireshark/Ethereal can be connected to this port, for example.
