NAT Traversal Capability and Keep-Alive Functionality With IPSec in IKEv2 Implementation

Free registration required

Executive Summary

Since IPv4 Private Networks are behind NAT (Network Address Translation) devices. So, to bypass the Binding Update and Binding Acknowledgment by NAT, the authors need to encapsulate it in UDP (User Datagram Protocol) Packets. Hence, the Dual Stack Mobile IPv6 should support NAT Traversal and Detection. So for proper securing and fully functionality of NAT traversal, it should be IP Security Protected. Paper presents design and implementation of NAT traversal capability and keeps alive functionality with IP Security in IKEv2 (Internet Key Exchange version implementation for proper Data Communication. It also implements how IPSec integrate with NAT.
