LANCOM 821+ is the ADSL2+ router that opens up broadband Internet access for entire networks in small and mid-sized enterprises and offices.
At the same time, the router provides all connected stations with a gateway to office applications such as e-mail, fax, or other ISDN services.
Features like the powerful stateful inspection firewall with Intrusion Detection and Denial-of-Service protection, detailed monitoring and billing functions for all workstations all
go to accentuate the professional character of this LANCOM router.
More Security.
The integrated firewall with the latest security functions such as stateful inspection, Intrusion Detection and Denial-of- Service protection will screen your network safely and reliably
from attacks from the Internet. A comprehensive range of backup options and high-availability functions over ISDN and VRRP are supplemented by bandwidth management, all of
which guarantees trouble-free operations around the clock.
More Professionalism.
The management systems LANconfig and LANmonitor are included and offer not only cost-effective remote maintenance of entire installations and highly convenient setup wizards,
but also full real-time monitoring and logging. Further, service providers benefit from the broad range of scripting methods and professional access for administrators via SSH,
HTTPS, TFTP and ISDN dial-in.
More Benefits.
Comprehensive installation wizards with preset input masks offer rapid installation of the various functions. LANconfig and LANmonitor as management software are included to
allow professional administration and convenient monitoring of all relevant parameters. For larger projects, rollout mechanisms and multiple individual administration accounts
are available.
More Reliability for the Future.
From the very start, LANCOM products are designed for a product life of several years. They are equipped with hardware dimensioned for the future. Even reaching back to older
product generations, updates to the LANCOM Operating System–LCOS–are available several times a year, free of charge and offering major features. LANCOM offers unbeatable
protection of your investment!

by checking the TACACS+ server’s database. CRON, action-table and script processing can be diverted to avoid TACACS+ to
relieve TACACS+ servers. Redundancy by setting several alternative TACACS+ servers. Configurable option to fall back to local
