Business VPN ADSL2+ router with WLAN for professional site connectivity 300 MBit/s, WLAN, 5 IPsec-VPN, 4-Port-Switch, USB 2.0
- Integrated ADSL2+ modem
- 5 integrated IPsec VPN channels, upgradable to 25, integrated hardware acceleration
- 300-Mbps WLAN as per 802.11a/b/g/n (draft 2.0)
- Secure WLAN compliant with IEEE 802.11i (WPA2/ AES) and Multi-SSID
- Stateful-inspection firewall with intrusion detection/denial-of-service protection
- Multiple interfaces: ISDN, USB-2.0 port, Ethernet, and serial port
The LANCOM 1821n Wireless provides everything you need for site connectivity: Offering 5 integrated VPN channels, which can be upgraded to 25 by means of a VPN option, it comes with an on-board ADSL2+ modem. The device connects directly to the Internet—no additional modem is required. A range of interfaces, including ISDN, four separable switch ports, serial port and USB-2.0 port, facilitate the connection to PBX systems and network devices; should the device be unattainable via IP, it provides alternative access to the configuration. Load balancing can use up to four WAN connections. Security is provided by high-quality security features such as the stateful-inspection firewall with intrusion detection and protection against denial of services.
And there's more: The new WLAN module works at 300 Mbps and achieves far greater ranges than the product's predecessor. The hugely improved coverage from the integrated MIMO technology allows entire offices to be networked, without requiring additional access points. Multi-SSID enables the definition of multiple user groups, which makes it simple to set up WLAN access for guests, who remain completely separated from the company's internal network.
