Research And Implementation Of Firewall Based On Mobile IPv6

With the high-speed development, computer network is used in many ways, such as politics, economy, and culture. Network is becoming an important part in our life. At the same time, network security is breaking open directly, network security is unparalleled regarded broadly nowadays. As one of the most important technology of network security, firewall technology is becoming an important way in the research of network security.IPv6 has some specialities, such as limitless address space, security support and mobility support. In future, more and more wireless equipments will connect to Internet and mobility should be the most important attribute of Internet, so mobile IPv6 will be a preferred scheme which can provide mobile communication.In order to ensure the security of signal and the transparency of communication between home network and mobile nodes, we propose a solution which specify how to use IPSEC information validate to protect mobile IPv6 signaling between mobile nodes and firewall. Firewall based on the solution can solve the problem which the signaling between home network and mobile pots cann' t through firewall and ensure the confidentiality of communication between home network and mobile nodes. And because the solution only establish IPSEC tunnel between firewall and mobile nodes, it consume less system resource and is more practicable. And the last part of the paper is the realization of this firewall under Linux operating system and the test of this firewall.
