Title: Improvement of Compatibility of IPsec with NAT
Abstract: An improved tunnel encapsulation method was proposed based on the analysis of the mechanism of Internet network layer security protocol IPSec. On the basis of encapsulating the original IP address of the host in the data packet and doing corresponding management of it at the opponent side and solving the incompatibility problem between IPSec and NAT the two sides of the communication can still configure their security policy flexibly. Compared with the solution method of Internet engineering task force, our method can keep the flexibility of security policy configuration without the loss of security and with adding a little spending.
