All You Need To Know About Cisco VPN Solutions



The Cisco Systems VPN Client is a software application that connects users to a virtual private network. It works by making remote resources of another network available in a secure way as if the user were connected directly to that network. Cisco aims to improve security and maintain productivity through VPN technology by helping connect offices, remote users, and business partners securely and affordably.

Their VPN solutions provide top-quality security through encryption and authentication technologies that protect exchanged data from unauthorized access and attacks. You can tailor the access rights to any trusted user or network administrator, add new sites or user without having to expand your current infrastructure, improve productivity by extending corporate networks, applications, and collaboration tools, and reduce communications costs while increasing flexibility.

Cisco VPN employs two different VPN technologies: site-to-site VPN and remote-access VPN. Site-to-site VPNs provide an Internet-based WAN infrastructure to extend network resources to branch offices, home offices, and business partner sites. All traffic between sites is encrypted using IPsec protocol. Remote access VPNs extend almost any data, voice, or video application to the remote desktop, emulating the main office desktop.

What Is Cisco Easy VPN?

Cisco Easy VPN is an IP Security (IPsec) VPN solution which centralizes all of your smart devices that supports Cisco, such as routers and smart appliances. This means that you can manage any device in your office even in remote areas through the VPN solution. It is made up of three components, namely the Easy VPN Client, Easy VPN Remote, and Easy VPN Server.

The Easy VPN Client lets the mobile users to create a remote access VPN connection to an Easy VPN Server. The Easy VPN Remote, or commonly referred to as the hardware client, enables the routers and other devices to establish a site-to-site VPN connection to an Easy VPN server without all the complicated remote-side configuration. The Easy VPN server accepts connections from the VPN Client and Remote and ensures that it is up-to-date before the connection is established. It is inter-operable with all VPN Client and Remote.

If you are managing a large-scale site-to-site and remote-access VPN network, the Cisco Easy VPN solution will definitely help you organize everything because of its easy-to-use and simple configuration. It supports quality of service (QoS) and multicast for the site-to-site VPN solution, plus the Dynamic Multipoint VPN (DMVPN) for dynamic routing protocols or direct spoke-to-spoke communications.

The Easy VPN Remote is available on Cisco 800, 1800, 1900, and 2800 Series Integrated Service Routers and Cisco ASA 5505 Adaptive Security Appliances. The Easy VPN Server is available on numerous Cisco IOS Software-based routers, including Cisco 1800, 1900, 2800, 2900, 3800, 3900, 7200 Series Routers and Cisco 7301 Router. It is also available on all Cisco ASA Adaptive Security Appliances.

The Enhanced Easy VPN is a new method for configuring Easy VPN using Dynamic Virtual Tunnel Interface (DVTI) instead of a crypto map, which is used by traditional Easy VPN. DVTI can be used on both the Easy VPN Server and Easy VPN Remote routers, and relies on the virtual tunnel interface to create a virtual access interface for every new Easy VPN tunnel. The configuration of the virtual access interface is cloned from a virtual template configuration, and the cloned configuration includes the IPsec configuration and any Cisco IOS Software feature configured on the virtual template interface, such as QoS, Network Address Translation (NAT), Context-Based Access Control (CBAC) firewall, NetFlow, or access control lists (ACLs).
