Application Solution And Safety Research Of A New VPN Secure Gateway

The deficiencies inherent of VPN technology and the increasingly complex network environment, make the traditional VPN security gateway development facing huge bottleneck, need breakthrough to keep pace with changes and developments within the VPN market demand. The topics will focus on analyzing the new VPN security gateways, from the exsited problems the VPN technology has, to provide a new type of model.The article provide the address server solution to fix the VPN problem which can't e in the whole dynamic IP environment; provide NAT-T solution to solve VPN can't penetrate NAT device; provide transparent mode to solve VPN can't be put on firework/router's back; provide dual-mode client VPN network to enhance IPSec protocol suitability; provide VPN acceleration solution to improve access VPN client; analize the security gateway system security to protect usage.Through the application of new models and new types of VPN security gateway with the technology, the paper solves long-standing VPN technical barriers to meet the diverse needs of the growing market. The gateway security system analysis also proves that the It is in line with the design standards of security system to meet the user's security gateway security needs, and can effectively enhance the overall security system.
