Remote VPN

•
•

Remote VPNs allow secure access to corporate networks from remote locations by establishing an encrypted tunnel over the Internet. They provide secure communications and access rights tailored to individual users, enhancing productivity by extending corporate networks and applications while reducing costs and increasing flexibility. The example configuration shows a remote client (R1) connecting to a VPN server (R3) using IKE and IPsec to securely access resources on R3's network.

Remote VPN Remote-access VPNs allow secure access to corporate resources by establishing an encrypted tunnel across the Internet. The ubiquity of the Internet, combined with today's VPN technologies, allows organizations to cost-effectively and securely extend the reach of their networks to anyone, anyplace, anytime. VPNs have become the logical solution for remote-access connectivity for the following reasons:  Provides secure communications with access rights tailored to individual users, such as employees, contractors, or partners.  Enhances productivity by extending corporate network and applications.  Reduces communications costs and increases flexibility. Example Remote VPN (Note: R1 able to reach R3.) Figure 1 Topology
