Lancom Systems 1751 UMTS LS61621/54235100 Manuel D’Utilisation

LANCOM 1751 UMTS

Scope of features: as of LCOS version 7.2

Certificate revocation lists (CRL)

CRL retrieval via HTTP

RAS user template

Configuration of all VPN client connections in IKE ConfigMode via a single configuration entry

Proadaptive VPN

Automated configuration and dynamic creation of all necessary VPN and routing entries based on a default entry for site- to-
site connections. Propogation of dynamically learned routes via RIPv2, if required. 

Algorithms

3DES (168 bit), AES (128, 192 or 256 bit), Blowfish (128 bit), RSA (128 or - 448 bit) and CAST (128 bit); MD- 5 or SHA- 1 hashes

NAT- Traversal

NAT- Traversal (NAT- T) support for VPN over routes without VPN passthrough

IPCOMP

VPN data compression based on LZS or Deflate compression for higher IPSec throughput 

LANCOM Dynamic VPN:

Enables VPN connections from or to dynamic IP addresses. The IP address is communicated via ISDN B-  or D- channel or with 
the ICMP or UDP protocol in encrypted form. Dynamic dial- in for remote sites via connection template

Dynamic DNS

Enables the registration of IP addresses with a Dynamic DNS provider in the case that fixed IP addresses are not used for the 
VPN connection

Specific DNS forwarding

DNS forwarding according to DNS domain, e.g. internal names are translated by proprietary DSN servers in the VPN; external 
names are translated by Internet DNS servers.

1364- byte packet size

all VPN figures with AES encryption and active VPN hardware acceleration

1470- byte packet size

61 Mbps

256- byte packet size

Router

IP and NetBIOS/IP multi- protocol router

VLAN

VLAN ID definable per interface and routing context (4094 IDs)

Q- in- Q tagging

Support of layered 802.1q VLANs

Advanced Routing and Forwarding

Separate processing of 8 contexts due to virtualization of the routers. Mapping to VLANs and complete independent 
management and configuration of IP networks in the device, i.e. individual settings for DHCP, DNS, Firewalling, QoS, Routing 
etc.

HTTP

HTTP and HTTPS server for configuration by web interface

DNS

DNS client, DNS server, DNS relay, DNS proxy and dynamic DNS client

DHCP

NTP

NTP client and SNTP server, automatic adjustment for daylight- saving time

Policy- based routing

Policy- based routing based on routing tags. Based on firewall rules, certain data types are marked for specific routing, e.g. to 
particular remote sites or lines.

Dynamic routing

Dynamic routing with RIPv2. Learning and propagating routes; separate settings for LAN and WAN
