Chapter 1: Introduction

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 Wireless DSL is equipped with appropriate protective 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.

1.3What 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 15.

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).

PC 1	server A
