technologies such as DSL (Digital Subscriber Line). But also a conventional ISDN line can be used.

The technologies of the individual participants do not have to be compatible to one another, as would be the case for conventional direct connections. A single Internet access can be used to establish multiple simultaneous logical connections to a variety of remote stations.

The resulting savings and high flexibility makes the Internet (or any other IP network) an outstanding backbone for a corporate network.

1.3Firewall

The integrated Stateful Inspection Firewall ensures an effective protection against undesired intrusion in your network by permitting only incoming data traffic as reaction to outgoing data traffic. The router’s IP masquerading func- tion hides all workstations of the LAN behind a single public IP address. The actual identities (IP addresses) of the individual workstations remain con- cealed. Firewall filters of the router permit specific IP addresses, protocols and ports to be blocked. With MAC address filters it is also possible to specifically monitor the access of workstations in the LAN to the IP routing function of the device.

Intrusion Detection

Break-in attempts into the local network or on the central Firewall are rec- ognized, repelled and logged by the Intrusion Detection system (IDS) of the LANCOM DSL. Thereby it can be selected between logging within the device, email notification, SNMP trap or SYSLOG alarms.
