The LANCOM 1721 VPN is a top model of the LANCOM line of highly integrated VPN networking components designed for secure connectivity for sites, branch offices or subsidiaries. With standard equipment including 5 VPN channels (25 optional), an integrated ADSL2+ modem, an ISDN interface for backup, remote maintenance and LANcapi applications, four separately controllable switch ports and a USB-2.0 host port, this router is suitable for a highly diverse range of applications.
More Security
The integrated firewall with the latest security functions such as stateful inspection, Intrusion Detection and Denial-of-Service protection is supplemented by dynamic bandwidth management and comprehensive backup, high-availability and redundancy functions over ISDN and VRRP. The integrated VPN gateway that fulfills the IPSec standard and optional hardware accelerator provide optimal security for connecting telecommuters and branch offices thanks to the high-security 3-DES or AES encryption and support of digital certificates.
More Management
The management systems LANconfig and LANmonitor are included and offer not only cost-effective remote maintenance of entire installations along with highly convenient setup wizards, but also full real-time monitoring and logging. What’s more, service providers benefit from the broad range of scripting methods and professional access with individual access rights for administrators via SSH, HTTPS, TFTP and ISDN dial-in.
More Benefits
The versatile functions for address translation and routing allow the connection of completely different networks over common infrastructure. Existing networks at partner companies, home-office workstations or subsidiaries can be integrated into the VPN without problem. With the option of port separation and a separate address range, your own web servers can be securely separated from the LAN. Optional SIP proxy and SIP gateway functions offer big savings through the use of existing data connections for voice transmission (VoIP telephony). The integrated ISDN interface allows remote field installations, dial-up access and CAPI featured functions such as fax services for all connected PCs. A USB 2.0 host interface can be connected to affordable USB printers which then become network capable.
More Certainty 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!
