LANCOM 7111 VPN – LANCOM 8011 VPN

Preface

Preface

Thank you for placing your trust in this LANCOM Systems product.

The top models of the LANCOM router series serve as extremely powerful Dynamic VPN gateways for medium-sized and large locations.

Due to the Fast Ethernet uplink, LANCOM devices are ideal partners for all connection variants.

Integrated LANCOM High Security Firewall

With 100 up to 1000 VPN channels the LANCOM router series offers enough capacity for high-bandwidth couplings (LANCOM 8011 VPN with hardware accelerator).

With the IPSec extension LANCOM dynamic VPN it is possible to connect branch offices with dynamic IP addresses (standard broadband connec- tion) at any time—even if the receiving station is not online.

DMZ ports and separate internet address ranges (without NAT) support the operation of your own web servers.

The IP quality of service functions provide dynamic bandwidth manage- ment, in particular for Voice over IP telephone systems, for critical appli- cations or for certain user groups.

Due to its N:N IP address mapping also existing networks can be inte- grated seamlessly into VPNs.

The provided management tools LANconfig and LANmonitor support a complete real time monitoring apart from comfortable remote mainte- nance of the branch offices.

Further highlights are the extensive Firewall features, for example the Stateful Inspection, Intrusion Detection and protection from Denial-of- Service attacks.

Regular free software updates of the LANCOM operating system LCOS are available at any time.

Security settings

For a carefree use of your device, we recommend to carry out all security set- tings (e.g. Firewall, encryption, access protection, charge lock), which are not already activated at the time of purchase of your device. The LANconfig wizard ’Check Security Settings’ will support you accomplishing this. Further informa- tion regarding this topic can be found in chapter ’Security settings’ →page 62.
