Lancom Systems 1681V 62001 Benutzerhandbuch

LANCOM 1681V

Scope of features: as of LCOS version 8.2x

Individual display pages (for blocked, 

error, override)

Response pages displayed by the content filter in case of blocked sites, errors or overrides can be custom designed. Variables 

enable the inclusion of current information such as the category, URL, and rating-server categorization. Response pages can be 

issued in any language depending on the language set in the user's web browser

Redirection to external pages

As an alternative to displaying the device's own internal response pages to blockings, errors or overrides, you can redirect to 

external web servers

License management

Automatic notification of license expiry by e-mail, LANmonitor, SYSLOG or SNMP trap. Activation of license renewal at any time 

before expiry of the current license (the new licensing period starts immediately after expiry of the current license)

Statistics

Display of the number of checked and blocked web pages by category in LANmonitor. Logging of all content-filter events in 

LANmonitor; log file created daily, weekly or monthly. Hit list of the most frequently called pages and rating results. Analysis of 

the connection properties; minimum, maximum and average rating-server response time

Notifications

Messaging in case of content-filter events optionally by e-mail, SNMP, SYSLOG or LANmonitor

Wizard for typical configurations

Wizard sets up the content filters for a range of typical scenarios in a few simple steps, including the creation of the necessary 

firewall rules with the corresponding action

Max. users

Simultaneous checking of HTTP traffic for a maximum of 50 different IP addresses

Router

IP and NetBIOS/IP multi-protocol router

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, VLAN, 

Routing etc. Automatic learning of routing tags for ARF contexts from the routing table

HTTP

HTTP and HTTPS server for configuration by web interface

DNS

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

DHCP

DHCP client, DHCP relay and DHCP server with autodetection. Cluster of several LANCOM DHCP servers per context (ARF 

network) enables caching of all DNS assignments at each router. DHCP forwarding to multiple (redundant) DHCP servers

NetBIOS

NetBIOS/IP proxy

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. Extended RIPv2 including 

HopCount, Poisoned Reverse, Triggered Update for LAN (acc. to RFC 2453) and WAN (acc. to RFC 2091) as well as filter options 

for propagation of routes. Definition of RIP sources with wildcards

VLAN

VLAN ID definable per interface and routing context (4,094 IDs)

Q-in-Q tagging

Support of layered 802.1q VLANs

ARP lookup

Packets sent in response to LCOS service requests (e.g. for Telnet, SSH, SNTP, SMTP, HTTP(S), SNMP, etc.) via Ethernet can be 

routed directly to the requesting station (default) or to a target determined by ARP lookup

COM port forwarding

COM-port server for DIN and USB interfaces. For multiple serial devices connected to it, the server also manages its own virtual 

COM ports via Telnet (RFC 2217) for remote maintenance (works with popular virtual COM-port drivers compliant with RFC 

2217). Switchable newline conversion and alternative binary mode. TCP keepalive  according to RFC 1122 with configurable 

keepalive interval, retransmission timeout and retries

Print server (USB 2.0)

Host port for connecting USB printers via RAW-IP and LPD; bi-directional data exchange is possible

IP

ARP, proxy ARP, BOOTP, LANCAPI, DHCP, DNS, HTTP, HTTPS, IP, ICMP, NTP/SNTP, NetBIOS, PPPoE (server), RADIUS, RIP-1, RIP-

2, RTP, SIP, SNMP, TCP, TFTP, UDP, VRRP

ADSL, Ethernet

PPPoE, Multi-PPPoE, ML-PPP, PPTP (PAC or PNS) and plain Ethernet (with or without DHCP), RIP-1, RIP-2, VLAN

ISDN

1TR6, DSS1 (Euro-ISDN), PPP, X75, HDLC, ML-PPP, V.110/GSM/HSCSD, CAPI 2.0 via LANCAPI, Stac data compression

UMTS/HSDPA*

UMTS/HSDPA with external module at the usb interface

*) Note:

A UMTS usb modem is not supplied. The support cannot be guaranteed for all modems available in the market. Supported UMTS
