DrayTek Universal Security Router with VoIP, built-in ADSL2+ modem, 802.11N Wireless, RJ45 WAN and USB WAN - DV2820VN

The Vigor 2820 series is DrayTek's latest premium ADSL and broadband router/firewall family, featuring an entirely new stylish case design and new DrayOS 3 operating system. Packed with features, the Vigor 2820 offers truly comprehensive ADSL connetivity and security.

Compatible with all variants of ADSL (include ADSLMax and ADSL2+) the Vigor 2820 can also be used for cable-modem and leased line applications thanks to its additional WAN port (Ethernet). A Gigabit Ethernet port on the LAN side provides high speed connectivity for your server (or uplink to a larger Ethernet Switch). Security features include content filtering, web application controls and a new object based firewall management system.

The Vigor 2820 Series 'V' models build on the established DrayTek VoIP pedigree by adding even more new feaures. Twin analogue phone ports and an FXO analogue line port provide full PSTN and VoIP integration on the same phones, via both the Internet and your regular analogue line. The two phones can be used independently and simultaneously for both incoming and outgoing calls.
