So, in site-to-site VPN architectures, VPN concentrators are typically employed. VPN concentrators can create and manage thousands of VPN tunnels concurrently. The term Security Gateway may also be used to refer to a VPN Access Server.įor large organizations, especially those with two or more geographically separated work sites, a standard VPN server cannot support the number of connections required, nor can it handle the volume of traffic generated by thousands of workforce users. Such entities may be referred to as an Open VPN Server or an Open VPN Access Server. VPN server software is sometimes created using the open source software model, which allows a community of software developers to modify and enhance the software functionality. In summary, a Virtual Private Network is a secure virtual connection established over an unsecure public network such as the Internet. Network.you can connect and communicate (network) with other computer resources and users (co-workers, clients, customers, and such). all your communications are encrypted and hidden from everyone other than those with whom you want to communicate you have a private connection to another network which is built in software rather than a dedicated hardware (cabled/wired) link. The VPN client (remote worker's computer) must first connect to the virtualized network element and authenticate (provide a username and password or use a certificate) before access can be established to the Corporate Network So to summarize the VPN concept, let's break it down. The VNF employs such protocols as point-to-point protocol (PPP) for connectivity and communications. It also hides the IP address and geographic location of the user from everyone else on the Internet. The network function creates what is known as a VPN tunnel between the client and the business network that hides the private data stream from the rest of the world. Most businesses, enterprises, and other organizations use VPN software to allow mobile, remote, and home-office workers to connect privately and securely over the Internet to the corporate network-with all its associated services such as printers, file servers, Intranet services, and so on.
