Virtual Private Networking

Flat rate pricing from service providers results in significant cost savings when comparing leased-line services with public facilities from carriers. As a cost-effective alternative to direct dial-in connections or leased lines, Virtual Private Networks (VPNs) create a new telecommunications capability by providing secure remote access across the public Internet or Frame Relay network.

secure intranet access using industry standard Layer 2 Tunneling (L2TP) and IP Security (IPSec) VPN technology.

VPN's support secure remote access to the home network LAN. A secure path, or “tunnel”, is set-up between the 2784 and the end user. Once the session is established, applications function as though a direct connection to the local LAN exists. Tunneling encapsulates private intranet traffic into the Internet,

By permitting the enterprise to use a public data network, VPNs take advantage of the Internet's global presence. Using the Patton 2784 NAU, mobile and SOHO users can create

while security enhancements control user authentication, authorization and encryption to assure confidentiality of all private information.
