7.2 C ONFIGURATION USING THE F ILTER W IZARD
The function of the packet filter of a device is to classify data packets in desired and
undesired data traffic and to initiate appropriate actions.
The packet filter can be started through the path Configuration > Packet Filter unless
it is started directly after the Setup Wizard.
The homepage of the packet filter allows to add new rule sets and to process existing rule
sets.
Note:
A rule describes the configuration of a specific filter instruction. A rule set can consist
of up to ten separate rules.
7.2.1 A DDING A R ULE SET
Adding a rule set first requires the selection of the layer over the respective Tab (1). In
the Transparent Bridge Mode, filtration on bridged Ethernet interfaces (Layer 2) is
necessary in most cases while in the IP Router Mode or when using the SERVICE modem it
is also possible to choose independent IP interfaces (Layer 3).
Bridged Ethernet interfaces (Layer 2):
Corresponding to the Ethernet filtration level. This setting makes possible, e.g. filtration by
means of Ethernet MAC addresses or network protocols not using IP addresses. Filtration
on the basis of IP protocol features however is also possible.
Independent IP interfaces (Layer 3):
On this level, filtration is only possible on the basis of IP protocol features because
between the interfaces of level 3 only IP data traffic takes place.
Click on the button Add a new rule set (2) to create or add a new or pre-configured rule
for the selected layer. A description of how to create a new rule set is given in the chapters
Define a new rule set on Layer 2 and Define a new rule set on Layer 3. The
chapter Load a pre-configured rule set describes the predefined rule set.
