The key technologies of SSL VPN (http://www.wjld.com.cn/) include: Web proxy, port forwarding, application conversion, and network connection (NC). Currently, most SSL VPN products are developed and implemented based on one or several of these technologies. So, for domestically produced SSL VPN products, which technologies are particularly important?
Firstly, the Web proxy technology. Since users need to access Web applications within the internal network and hope for as simple an access method as possible, only with Web proxy technology can an SSL VPN product achieve 100% zero-client, providing users with the simplest access method. Therefore, Web proxy technology is a necessary technology for domestic SSL VPN products and also one of the important standards for evaluating the professionalism of SSL VPN products.
