Overview

Vigor 2950 High-Performance Firewall
The Vigor 2950 Security Firewall combines Internet security, high throghput and high capacity VPN capabilities. For remote teleworkers and inter-office links, the Vigor 2950 can support up to 200 simultaneous VPN tunnels. Encryption and authentication is all handled by a dedicated VPN co-processor, thus maintaining maximum router performance. The Vigor 2950 also provides high-security firewall options with both IP-layer and content based protection.

Dual Wan

 Draytek 290 daul wan port

For Internet connectivity protection, the Vigor 2950 has two WAN ports which can be used in failover mode (secondary ISP used if the primary ISP fails) or in load-balancing mode, where the two ISPs can share the Internet loading. Specific rules can be set for routing traffic via specific WAN connections, or automatic balancing will make best use of resources.

SSL VPN

 VPNs (Virtual Private Networks) enable you to link two remote computers or networks securely using the public Internet. An encrypted tunnel is created to carry your private data between the two sites. Tunnels making use of PPTP, L2TP, AES and IPSec protocols have been available on Vigor routers for many years and provide a simple to set up solution for your site-to-site or teleworker VPNs. SSL VPNs provide a new method for teleworker to central site VPN, providing great convenience, low TCO and simplicity where other methods may not be possible.

The need for SSL VPNs
One potential drawback of using the above methods for a Teleworker-to-central site VPN is that they need compatiable protocol stacks at each end (e.g. an IPSec client or hardware) and most importantly those protocols need to be freely passed by your local host network. This isn't normally a problem where you own the computers and the network in use and you can install any client, software or hardware you choose, as well as allowing any traffic types you like. Where it can become a problem is where you are using someone else's computer or network where either you cannot use the O/S VPN client, or the host network blocks VPN protocols or makes them unreliable. This is most commonly a problem when using WiFi hotspots or other public Internet access methods (hotels, conference centres etc.).

You may already have heard of SSL previously, and you have almost certainly used it. SSL (Secure Sockets Layer) is the protocol used by all web browsers for accessing 'secure' web sites. You will have used secure web sites whenver you have used your credit card online or accessed your banking web sites, for example. SSL is supported by all web browsers, and as it is so commonly used, all hotspots and other public Internet will always allow SSL to pass properly. By using the SSL protocol for your telework VPN tunnel you therefore have some important benefits:

Another advantage of web based SSL VPN is that your host Vigor router presents the user with his/her login page to the network within their browser and then can provide access only to the web based applications or local servers which you allow as opposed to a regular VPN which connects the user to the network directly for access to any resource which is accessible locally. No TCP/UDP ports have to be opened on your host router; if the user cannot login to the VPN, they won't get access.

As mentioned previously, an SSL VPN uses your standard web browser; this means that for your web based applications running at your office (webmail, Intranet, Thin Clients etc.) SSL VPNs work really well for this access method, which is called 'SSL Web Proxy' mode. A very common application for SSL VPN is remote desktop. By using the Windows 'Remote Desktop Web Connection', your office desktop will be accessible from your web browser whereever you are and whoever's computer you're using. In addition, by using Vigor web proxy, you can browse external web sites via the tunnel, thus bypassing any local web site blocking policy (content filtering or local polcies). If you are familiar with 'port redirection' or 'open ports setup' on Vigor routers, SSL Proxy to your internal web services is very similar in concept to this except that the data passes through a secured tunnel, hence increasing security and privacy.

SSL VPNs beyond the Browser
Using the web browser for your remote access is great for accessing web-based applications (intranet, webmail, remote web desktop etc.) but it does not provide access to the actual network directly, for example for shared directory access, network resources or other applications which are not browser based. Only data or applications which are available in your web browser locally are available remotely via the SSL Proxy (see above).

For full network access, DrayTek provide an Active-X Tunnel plug-in (a VPN client, effectively) which can transfer at the network layer, making a fully VPN tunnel. This is called SSL Tunnel mode. This plug-in is downloaded automatically by your browser from the host Vigor router when you log into the SSL VPN and select Tunnel mode. You are then fully connected to the remote network for direct network resource access. In this way, you are no longer limited to running web-based applications and can access shares and other network resources.
