 In a scanty local area network LAN with few, very trusted users and good physical security, clear-text data going over network wires is not likely to elevate security-related risk very much. The further this data is transmitted, the greater the risk because there are more distinct points at which clear-text data can be captured without authorization. Sending clear-text data from one point to another over a public network, however, raises security-coordinated concerns to an entirely different level. Virtual Private Network VPNs are secure tunnels over a public network, most notably the Internet. This secure tunnel allows two private, internal networks to spread over the public network without compromising the communications that flow over them. The two networks may be corporate LANs, a single remote machine from the vast pool of road warriors that your company has, or an employee working from home.
From a consumer perspective, each user is on the internal network. Each has access to all the resources available to someone who is physically connected to the regional LAN. The speed or bandwidth is probably the only noticeable difference in a true...

 This article designed to show you how to setup configure VPN access in order to enable remote access to your home computers from the Internet. This article is designed for CCNA students, network engineers, and anyone looking to the VPN Passthrough feature. This article falls under the CCNA syllabus's objective "Explain and select the appropriate administrative tasks required for a WLAN". VPN technology allows you to link to your home network from the Internet securely. Once the VPN connection is established, a tunnel is created between your urgent computer and the other device on your home network. Data exchanged through the VPN tunnel is encrypted. Thus, your data can traverse the internet securely.
Some of the VPN protocols are IPSec, PPTP, and L2TP. In order to establish VPN connections to your internal network, you should configure the router to allow the VPN protocols you are actually using to pass through its firewall.
Now, let us expect that you want to access your network PCs from the internet, and you have a static public IP address configured on your Linksys router (if you do not have a static public IP address, then you can...

 Businesses nowadays have come about global market and logistics. Companies are apt for rapid, secure and trustworthy communications. During the growth of internet, businesses are frequently expanding their own networks. It was earlier in time when intranets came into existence. These are sites designed only for the use of company employees. Until recently, companies create their own Virtual Private Networks (VPN) to accommodate the needs of remote employees and distant offices. VPN services can be used for secure, anonymous surfing, anonymous mp3 and movie download, safe access to adult sites, unblock VoIP (skype), and bypass any restrictions to view any site. A VPN or virtual private network is a network that is layered on top of a basic computer network and uses a public telecommunications infrastructure like the internet. Primarily, it uses virtual connection routed through the internet from a company's private network to the remote site or employee.
VPN is provided to individual users and remote offices for them to have a secure access to their organization's network. Furthermore, companies and organizations use VPN to send voice, video

 Most people don't know you can change your IP with various programs, and even fewer know how to change your IP address with a virtual private network (VPN). The actually IP changing part is easy - VPNs are not complicated. But understanding why is a bit of a mental jump.
You see, your IP address is fastened to your computer, and there's a lot that you can tell about YOU by analyzing your IP address. Stuff like browsing history, which operating system you're utilizing, e-mail content, location, and other more. I can't tell you exactly how it's done, but the scary thing is that there are people that do - and you don't know to be a computer genius to find out. FREE and readily available software is available to help you trace other users on the same network as you. By monitoring and filtering traffic over s shared network, you can sneak passwords, login credentials, and other sensitive information. Heck, there's even a Firefox addon to help you do this! Changing your IP address by using a VPN prevents this.
When you change IP with a VPN you protect yourself on a couple levels. For one, you borrow an IP address from another computer. This means that the activity of your computer...
