Information Technology: VPN

KSC Virtual Private Network VPN Virtual Private Networks (VPN) allows access to your network from remote locations. The connections (tunnels) can be from one office network to another, an on the road sales person or an employee working from home. All the VPN systems that we deploye have encryption and security protocols built in.

There are two common implementations for a VPN: Site-to-Site and Client-to-Site.

Site to Site
Some office configurations require sharing information across multiple LANs. Initiating a secure VPN tunnel between two office gateway devices allows sites to share information across the LANs without fearing that outsiders could view the content of the data stream. This site-to-site VPN is a one-to-one VPN tunnel. Two servers or routers set up an encrypted IP tunnel to securely pass packets back and forth over the Internet. The VPN servers create a logical point-to-point connection over the Internet. Routing can be configured on each gateway device to allow packets to route over the VPN link or out the default network link.

Client-to-Site When a client requires access to a site's internal data from outside the network's LAN, the client needs to initiate a client-to-site VPN connection. This will secure a path to the site's LAN, allowing the client to access a private network address. The client-to-site VPN is a many-to-one VPN tunnel. One or more clients can initiate a secure VPN connection to the VPN server, thus securely accessing internal data from an insecure remote location. The client receives an IP address from the server and appears as a member on the server's LAN.

VPN can reduce wide area networking costs by eliminating the need for private dedicated connections.
