 Atheros Super-G WLAN und ISDN DrayTek Vigor 2800Gi Router and the World Wide Web (WWW)
The ADSL or ADSL2/2+ Routers of the DrayTek Vigor 2800 Series will get
directly connected to the splitter of your Telephone Company/Internet
Service Provider. The required RJ-45 ethernet cable is included in the
package and a separate DSL Modem is not necessary. To make sure that no
intruder will be able to gain access to the machines of your local
Ethernet the WAN and the LAN interfaces of the DrayTek Vigor 2800Gi
Router are seperated physically. The DrayTek Vigor 2800Gi Routers support
a Downstream of up to 24 Mbit and are compatible to the DSL Services of
the most established Internet Providers. If you dont know the necessary
DSL parameters for your ADSL line the DrayTek Vigor 2800Gi will auto
detect them.
The integrated ISDN BRI makes the DrayTek Vigor 2800Gi router compatible with Euro ISDN and you can simply connect it to your NTBA. This Feature makes sense as long as you dont have a DSL or other Broadband Connection available in your area. Just use the DrayTek Vigor 2800Gi a a simple ISDN Router. Of course you can use the ISDN interface of the router as a Dial-Backup solution. In case of a DSL/Broadband connection failure the DrayTek Vigor 2800Gi Router starts an internet connection by using ISDN. As soon as the DSL/Boroadband connection is available again the router drops the ISDN connection and dials in using Broadband services again! (Note: Using ISDN may produce additional online costs!!) Furthermore you can use the ISDN interface for building LAN-to-LAN connections or for simple RAS (Remote Access) Dial-In/Out to your company or home network. Bandwidth Management and VLANThe DrayTek Vigor2800Gi Router does support VLAN functionality. Each hardware ethernet port of the Router can be assigned to a virtual LAN so the exchange of data between some clients of your local Network can be restricted to machines that are in the same VLAN only. This gives you the possibility to separate single parts of you local Network. For example you can seperate your Home Office machines/clients from the machines/clients your family uses while internet access, printers or servers are still available to all the local machines. Additionally you do have the possibility to define the maximum bandwitdh for each of the hardware Ethernet ports of your DrayTek Vigor 2800 Series Router. You can limit the Upstream/Downstream for each of the hardware Ethernet ports of the Router and make sure that noone uses all of the available DSL bandwidth for Filesharing while you can't send out your important Email. Security - IP Firewall, DoS Prevention, URL-FilterSecurity comes first ans thats why the DrayTek Vigor 2800Gi Router owns an integrated Firewall! These Firewall features have been tested good by certain Computer Magazines worldwide. The Draytek Firewall allows the configuration/creation of IP Filter Rules and Sets. With this powerful feature you will be able to have complete control about what and which data/content will be allowed to pass through to the internet or will get blocked by the DrayTek Firewall. This way you can filter certain internet content or even complete services and applications. Hacker intrusion attempts will get blocked by a rich set of DoS (Denial of Service) functions also being a part of Drayteks security features. Those attempts will be made way more difficult and get logged by the DrayTek Router itself. You can also configure an Email Alert in case of someone trying to get access to your local Ethernet illegally. The URL Filter features of the DrayTek Router allow you to Filter Internet content by user definded keywords..and you also have the possibility to block certain file types like .exe, .zip, java, active x, etc.! The Vigor itself detects this filetypes and automatically prevents them from getting downloaded to your local machines if you want. Of course you can also block complete Websites by URL or certain keywords. The Router checks in realtime if any content that matches one of the configured Keywords shell be accessed by one of your local machines and then blocks those contents or URLs/Websites. With the implemented timer functions you will be able to block certain content only at pre defined times of the day or apply thos restrictions to certain IP Adresses of your LAN or certain subnets. WLAN Access Point 802.11g / Super-GThe DrayTek Vigor 2800Gi is compatible with the IEEE802.11g and IEEE802.11b standards and allows a maximum WLAN transfer speed of up to 108Mbit/s. With its two external and detachable antennas it always provides you an optimum wireless LAN performance.
Additional MAC-Hardware address verification gives you the
possibility to make your wireless LAN even more secure. Each network
client has a so called Hardware-MAC address. You can specify certain
MAC addresses within the configuration menu of the DrayTek Router. This
way only those clients you specified will be allowed to access your
wireless network. All other clients will get rejected by the DrayTek
Vigor 2800Gi Router. Furthermore the DrayTek Vigor 2800Gi Router of course supports WPA/WPA2 and or WEP (64/128) encryption for securing your wireless LAN. This way no intruder will be able to snoop your WLAN or get access to your important data. Two more reasons for chosing the Vigor Router: Radius Server authentication and VPNoW (VPN Over WLAN). VPN over WLAN allows you to use a VPN Tunnel between your WLAN client and your DrayTek Vigor 2800Gi routers access point for additional security. Providing you everything you may expect from a router it is possible to deactivate the WLAN interface completely or activate/deactivate the wireless LAN by timer. This way you can easily activate/deactivate the WLAN on certain days and timesautomatically. (Monday - Friday 8-18 active = other days inactive). SUPER-G FeatureThe implemetation of the Atheros chipset makes the DrayTek Vigor Router capable of supporting the Super-G feature. This feature allows a maximum WLAN data transfer of up to 108MBit/s. Super-G utilises the compatible 802.11e, 802.11a plus 802.11b and 802.11g standards and kind of doubles the regular WLAN speeds because of an own way of compression and bundeling the WLAN data pakets. WPA2 EncryptionWPA2 encryption is actually the best possible method for securing your wireless network. Based on the IEEE standard provides the DrayTek Vigor 2800Gi Router the most effective protection while using FIPS 140-2 AES encryption algorithms. Based on your decision encryption between 128 and 256 bit is possible. Regular WPA encryption provides only medium security because of only using RC4 encryption and you can call this outdated! WPA2 encryption with AES is also used by Government and Authorities worldwide to encrypt data and documents and with the possibility to use a Key/Passphrase that is can have up to 63 signs including numbers and ASCII characters this kind of encryption today is still un-crackable. VPN-Server for up to 32 simultaneous VPN-TunnelsThe DrayTek Vigor Router Series do support VPN (Virtual Private Networks). This gives you the possibility to connect two or more different locations (like a head office and a branch office(s)) through the internet and a so called VPN Tunnel. This way you can easily access remote network resources like files, data or servers and applications. The Draytek Vigor 2800Gi Router is able to manage the VPN connections automatically. That means you can define if the router shall initiate the VPN connection or wait for incoming connections or do both of them. Utilising DDNS (Dynamic DNS Services) grants you a steady connection even if you dont own a leased line or do not have an own static IP Adress. The DrayTek Vigor 2800Gi Router can act as VPN server or VPN Client. This way you will be able to configure up to 32 simultaneous VPN connections. (The connection speeds of course depend on the speed of your Internet Service and which encryption you choose for the deifferent VPN Tunnels) To establish a VPN connection you need at least one DrayTek Vigor 2800Gi Router and a VPN Client Software but also connecting more DrayTek Vigor 2800Gi Routers via VPN is possible. DrayTek provides several kinds of encryption methods to make sure your data that passes the Internet/VPN Tunnel will be safe and getting transferred with maximum security. When it comes to the safety you can chose between PPTP, L2TP or IPSec and chose DES, 3DES or AES ancryption algorithms. Of course "Main mode" and "Agressive mode" are supported as well. As an additional Feature the DrayTek Vigor 2800Gi Router allows you to generate and/or import own Security-Certificates. These certificates will then be used for IPSec authentication. LPR/LDP USB-PrintserverThe DrayTek Vigor 2800Gi Router owns an USB Port for Printserver functionality. Just connect a USB Printer to that port and you can share this USB Printer in your local Network environment.
Depending on the used Driver the PrintServer supports the following operating systems: Router Configuration / ManagementThe Router Configuration and or Management is kind of simple. Just use your standard Web-Browser, enter the local IP-Adress of the Router and after Password verification you are in the Web-Configurator of the Router which provides you a simple Interface to configure most of the features and functions of the Router.
The backup and restore of configuration data is of course supported!
Furthermore there's also the possibility of remote configuration of the
Router via Web-Browser or Telnet. NAT / Port Redirection / Open Ports / DMZ-HostThe most generic function of Vigor router is NAT. It creates a private subnet of your own. The DrayTek router will talk to other public hosts on the Internet by using a public IP address and talking to local hosts by using its private IP address. What NAT does is to translate the packets from public IP address to private IP address to forward the right packets to the right host and vice versa.
Furthermore you need the NAT Funtionality of the Router to make
Services running in your LAN accessible through the Internet! (FTP
Server, WEB Server etc..) Example: You want to set up a FTP Server
where you and your colleagues can share/upload and download files. This
Server is running on a local Computer in your local Network that has
the IP Adress 192.168.1.100. Port Redirection allows you that every
Packet arriving at the Routers WAN Port using the TCP/IP Protocol and
Port 21 (which is the standard Port for FTP Transfers) will pass the
Router and reach the local machine with the IP Adress 192.168.1.100. The Open Ports function allows you to redirect not only a single Port to a certain machine of your LAN.. you can redirect complete Port Ranges! This is an important feature for kind of any multimedia application you might want to use. (Online Games, Filesharing like BitTorrent and eMule, Messenger Software etc..) The DMZ Feature allows you to redirect any traffic that reaches the WAN Port of your DrayTek Vigor Router to only one machine. That means that this machine is in the DMZ (de-militarized zone). Using the DMZ Function allows you to specify one machine of your local Network beeing reachable for all requests from the internet. This machine then is not protected by the Vigor Routers Firewall no more and acts like it is kind of connected directly to the internet. DynDNSIn general you will receive a new WAN (public) IP Adress from your Internet provider dynamically as soon as you connect to the Internet (except you have 1 or more dedicated and/or fixed WAN IP Adresses) That means your WAN IP Adress will change every time you get connected to the Internet. (Most providers will disconnect you once each 24 hours). This prevents you from being reachable via one IP Adress for more than 24 Hours. For the fact that you are running a FTP Server everyone who wants to connect to this FTP Server will have to know your "actual" WAN IP Adress. This is where DynDNS comes pretty handy. Just register with one of the free DynDNS providers that are supported by the DrayTek Vigor Router like www.dyndns.org! With your registration you can chose a/your personal URL if it's not already been registered by someone else. (Example: myhome.dyndns.org) Once you registered an account and your personal URL you/your local network will be reachable around the clock using the DynDNS Feature of the DrayTek Vigor Router. Just configure the DrayTek Router and enter the data registered with the DynDNS Service and the router will synchronize your actual WAN IP Adress with the URL you have registered (Example: www.myhome.dyndns.org). This way it is very easy for you to set up FTP Servers, WEB Servers, a VNC Server etc.. and make them accessible 24 hours a day.
