Internet access share and the simulation under the Dr. COM authentication environment

In order to meet the flexible access requirements between internal and external enterprise network, the improved Internet connection share scheme based on RRAS and NAT was designed. The simulation of the company network based on VMware virtual machine was carried out, and Internet access share of host and mobile terminal under the Dr. COM broadband authentication environment was successfully realized. Compared with traditional network access scheme, without purchasing dedicated hardware routers, the improved scheme has some advantages, such as the lower cost, the strong scalability of hardware and software, the flexible networking, etc, which was especially suitable for small and medium enterprises. This scheme provided the beneficial reference about studying Internet access for engineering and technical personnel.
