Figure 14: Configuration  Packet filter  Tab „Layer 2"
This is the window for the manual configuration of firewall filter rules based on Layer 2 (MAC layer). The
screenshot shows the firewall settings as delivered with the 2 default rules "Allow_L2*" and „ARP*" (Address
resolution protocol). The rule Allow_L2* allows transmitting any Ethernet frame type (*) and any traffic
regardless the direction (source and destination mac address =*). The result is that - on delivery - the firewall
is "open" for layer 2.
