Implementation of IPsec-VPN Tunneling using GNS3

VPN and IPsec

Simple-VPN: Simple IPsec Configuration

The IPsec protocol promised easy, ubiquitous encryption. That has never happened. For the most part, IPsec usage is confined to VPNs for road warriors, largely due to needless configuration complexity and incompatible implementations. We have designed a simple VPN configuration language that hides the unwanted complexities. Virtually no options are necessary or possible. The administrator speci...

IPsec/VPN security policy correctness and assurance

With IPSec/VPN policies being widely deployed, how to correctly specify and configure them is critical in enforcing security requirements. Under current practice, IPSec/VPN policies are usually specified manually by system administrators and thus prone to errors. However, dynamic aspects in the network may interfere with the existing policy set up and thus cause unexpected conflict. To deal wit...

Secure VPN Based on Combination of L2TP and IPSec

This report is written to provide a method of building secure VPN by combination of L2TP and IPSec in order to meet the requirements of secure transmission of data and improve the VPN security technology. It remedies the secured short comes of L2TP Tunneling Protocol Tunneling Protocol and IPSec security. Simulation and analysis show that the construction method can improve the security of data...

Performance of Multimedia Applications with IPSec Tunneling

The concept of Virtual Private Networks offers a simple and cheap alternative to dedicated secure networks in corporate networks and Internet environments. The choice, however, of authentication and encryption techniques and protocols affect issues such as data throughput and performance throughout the network. This paper looks into the effects of video and audio streaming on performances, whil...
