LANCOM 1821n Wireless
Scope of features: as of LCOS version LCOS 7.7x
Routing functions
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
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
COM port server
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)
USB print server
Print server (USB 2.0) Host port for connecting USB printers via RAW-IP and LPD; bi-directional data exchange is possible
LAN protocols
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
Rapid Spanning Tree 802.1d Spanning Tree and 802.1w Rapid Spanning Tree support for dynamic path selection with redundant layer 2 connections
WAN protocols
ADSL, Ethernet PPPoE, PPPoA, IPoA, 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
Interfaces
WAN: ADSL ADSL over ISDN compliant with ITU G.992.1 Annex B (compatible to Deutsche Telekom U-R2 connections) or ADSL over POTS
compliant with ITU G.992.1 Annex A
WAN: ADSL2+ ADSL2+ over ISDN compliant with ITU G.992.3, ITU G.992.5 Annex B (ADSL2+) or ADSL2+ over POTS compliant with ITU G.992.3
and ITU G.992.5 Annex A (ADSL2+)
Ethernet ports 4 individual 10/100-Mbps Fast Ethernet ports; up to 3 ports can be switched as additional WAN ports with load balancing
- freely configurable Each Ethernet port can be freely configured (LAN, DMZ, WAN, monitor port, off). LAN ports can be operated as a switch or
separately. Additionally, external DSL modems or termination routers can be operated as a WAN port with load balancing and
policy-based routing. DMZ ports can be operated with their own IP address range without NAT
USB 2.0 host port USB 2.0 full-speed host port for connecting USB printers (USB print server) or serial devices (COM port server); bi-directional
data exchange is possible (max. 12 Mbps)
ISDN ISDN BRI port (S0 bus)
Serial interface Serial configuration interface / COM port (8 pin Mini-DIN): 9,600 - 115,000 baud, suitable for optional connection of analog/
GPRS modems
External antenna connectors Two reverse SMA connectors for external LANCOM AirLancer Extender antennas or for antennas from other vendors. Please
respect the restrictions which apply in your country when setting up an antenna system. For information about calculating the
correct antenna setup, please refer to www.lancom-systems.com
Management
LANconfig Configuration program for Microsoft Windows, incl. convenient Setup Wizards. Optional group configuration, simultaneous
remote configuration and management of multiple devices over ISDN dial-in or IP connection (HTTPS, HTTP, TFTP). Configuration
program properties per project or user. Automatic storage of the current configuration before firmware updates. Exchange of
configuration files between similar devices, e.g. for migrating existing configurations to new LANCOM products. Detection and
display of the LANCOM managed switches
LANmonitor Monitoring application for Microsoft Windows for (remote) surveillance and logging of the status of LANCOM devices and
connections, incl. PING diagnosis and TRACE with filters and save to file. Search function within TRACE tasks. Wizards for
standard diagnostics. Export of diagnostic files for support purposes (including bootlog, sysinfo and device configuration
without passwords). Graphic display of key values (marked with an icon in LANmonitor view) over time as well as table for
minimum, maximum and average in a separate window, e. g. for Rx-, Tx, CPU load, free memory. Monitoring of the LANCOM
managed switches
WLANmonitor Monitoring application for Microsoft Windows for the visualization and monitoring of LANCOM WLAN installations, incl. Rogue
AP and Rogue Client visualization
