Small business Internet- access router for ADSL2+
- Stateful-inspection firewall with intrusion prevention
- Integrated ADSL2+ modem for speeds of up to 24 Mbps
- Optional SIP proxy and SIP gateway functions

The LANCOM 821+ serves as a highly integrated networking component for small businesses and managed networks. This single device offers all of the functions necessary for secure connectivity of external sites or smaller branch offices.
More security.
The integrated firewall with the latest security functions such as stateful inspection, intrusion prevention and Denialof-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.
The versatile functions for routing and address translation allow the connection of completely different networks over common infrastructure. Optional SIP proxy and SIP gateway functions offer big savings through the use of existing data connections for voice transmission. The integrated ISDN interface allows remote field installations, dial-up access and CAPI featured functions such as fax services for all connected PCs.
