This is a super crazy device which can offer you everything in one go. It gives you an Internet Connection running on an ADSL2/2+, 108 Mbps connection for internet access, Voice over IP, a built-in firewall, Virtual Private Network (VPN) connections and Ethernet switch capabilities. Along with that you can create and maintain several Virtual LAN's or VLAN's with Quality of Service (QoS) supporting at maximum 32 VPN tunnels plus a USB printer port and content filtering which is supported with all ADSL technologies. With such capabilities who needs a hardware router now. The product has been marketed for residential and or SOHO (Small Office - Head Office) and business users. The device gives you a very good download speed of 12 Mbps with ADSL2 and 24 Mbps with ADSL2+ technology (which ever you enable). This device can make your internet download experience a fascinating fairy tale. Quality of Service (QoS) feature can make you reserve a good amount of bandwidth for any dedicated service like SMTP or POP3 guaranteeing mail flow every time. Pick any service, set the priority and leave the rest on QoS. You will get exceptional call quality when using VoIP, due to big bandwidth availability. If you know your destination then use the Microsoft windows integrated NetMeeting software to dial the other IP address and speak for as long as you can. This conversation can be protected when going through a VPN tunnel stretched between source and destination Draytek Vigor 2800VG. The device is compatible with 802.11x blends of Wi-Fi and provides an extra boost on signal strength and range with its twin extra-gain antennas. It supports the industry standard WEP and TKIP/WPA and AES/WPA2 encryption methods for your Wi-Fi Traffic. Bring in VPN with Wi-Fi and you can now use VPN encryption standards DES/3DES. Tighten the security further by implementing MAC level filtering and SSID Stealthing making your device almost invisible from any external threat. Internally you can use the Wireless LAN isolation and Wireless Distributive System with universal VLAN functionality. Along with regular NAT feature this firewall does a bit of state-full packet filtering, which mean it will look into each every packet's header and body to identify if the a legitimate one or not in a 'keep-state' method getting the acknowledgements intact. If a packet looks unsolicited to the firewall it will not be allowed to get through automatically protecting your network from any DOS (Denial of Service) or DDOS (distributed Denial of Service) attacks and any form of IP spoofing. User can also define customer filters to add more security to their customer application server. Keep the syslog logging enabled to get the list of potential unsolicited attacks to the router's IP.
