More About VPN
Virtual private network technology (VPN) is based on the idea of tunneling. VPN tunneling basically involves establishing and maintaining a secured network connection in which packets are constructed in a VPN protocol format and subsequently are encapsulated within some other base or carrier protocol. They are then transmitted between VPN client and server, and finally de-encapsulated on the receiving side. The most common form of VPN Tunneling is via PPTP (Point-to-Point Tunneling Protocol). The concept is illustrated in the diagram bellow.
A VPN will give you a secure connection which is a great addition to a firewall and antivirus. Antiviruses and firewalls control what is on your computer but once the information leaves your computer it is no longer safe. They also provide internet anonymity, internet security, and allows for internet freedom depending on your location in the world. We offer various VPN Services all with secure encrypted connections. Unlike using a proxy site that is very limited, our VPN services are compatible with pretty much any internet application such as Dreamweaver, Internet Explorer, Firefox, Skype, Outlook Express, Net2Phone, MSN, ICQ, and many more!
It is really simple to use with no additional software required just sign up. With our VPN services you get to surf in privacy and will not have to worry about logs being kept on your surfing habits. Internet service providers regardless of your location on the globe, keep logs of your internet online activities, what you do online, every click, every page you visit, everything is logged and archived for months or longer.
Countries such as Belize, China (Shenzhen), Thailand, UAE (United Arab Emirates - Dubai Abu Dhabi), Egypt, Pakistan, Jordan, Bahrain, Kuwait, Qatar - Doha, Palestine, Oman, Lebanon, Yemen, Mexico, Brazil or other Middle Eastern Countries, regulate what you can or cannot access online. VoIP (Voice Over Internet Protocol) is blocked which means that Skype, Net2Phone and other similar programs that rely heavily on this function cannot be used.
SSL VPN is a type of VPN that allows users to establish safe and secure remote access sessions from practically any internet connected browser. SSL functions between the Transmission Control Protocol (TCP) layer and Application Layer protocols.
SSL VPN offers flexibility, ease of use and secure, remote access to telecommuters, partners and customers who can access the corporate network from multiple locations including home, client networks, public kiosks, and hotspots over different devices like laptops, mobile devices and home and public desktops. This makes SSL VPN unique in providing anywhere, any device remote access which is not possible with other VPN solutions.
SSL uses TCP port 443, which is generally opened and will work through firewalls without any particular configuration. This means that SSL VPN will work in the situations that normal PPTP and L2TP VPN is blocked.
SSTP VPN is based on SSL rather than on PPTP or IPSec and uses TCP Port 443 for relaying SSTP traffic. It provides a tunnel where it sends PPP or L2TP traffic through an SSL channel. Although it is closely related to SSL the two cannot be directly compared because SSTP is only a tunneling protocol.
SSTP increases the coverage area of VPN connection which is ideal for places like Oman, Belize or even offices and schools. It establishes a connection over secure HTTPS and this allows clients to securely access networks behind routers, firewalls and/or web proxies not being concerned with port blocking issues.
Blocking issues in relation to GRE port blocking (Uses TCP Port 443) or ESP port blocking via a firewall or NAT router preventing the client from reaching the server will no longer be a problem. SSTP users will be able to connect to the internet from anywhere in the world.
