Denial-of-Service Protection
Attacks from the Internet can be break-in attempts as well as attacks with
the aim of blocking the accessibility and functionality of individual
services. Therefore a LANCOM router is equipped with appropriate protec-
tive mechanisms, which recognize well-known hacker attacks and which
guarantee the functionality.
Quality-of-Service / Traffic management
The generic term Quality-of-Service (brief: QoS) summarizes the functions
of the LANCOM which guarantee certain service qualities. The advantage
is that the QoS functions can take place by means of the existing powerful
classification methods of the Firewall (e.g. limitation of subnetworks,
single workstations or certain services).
Guaranteed minimum bandwidths give priority to enterprise critical appli-
cations, VoIP PBX installations or certain user groups.
More details about the function of the Stateful Inspection Firewall of
your LANCOM router can be found in the reference manual on the
LANCOM CD.

What does a router do?

The following sections describe the functionality of routers in general.
The functions supported by your device are listed in the table 'What
can your LANCOM router do?' →page 17.
Routers connect LANs at different locations and individual PCs to form a Wide
Area Network (WAN). With the appropriate rights, any computer in this WAN
can access other computers and services of the complete WAN (as with 'PC 1'
accessing 'Server A' in the remote LAN in the diagram).
