In response to security concerns caused by the increasing popularity of the Linux kernel domestic operating systems

while the network security applications lacked

analyse the dual stack technology of IPv4 to IPv6 transition technology

study the Linux kernel network stack structure

use the Linux kernel Netfilter framework

combine with the white list strategy

design and implement a host network management system.This system achieve the purpose to management and control the dual stack host network data. Experiments show that the system can be nondistinctivet control the two kinds network data flow

to facilitate the network security management of Linux host and thus improve the network security.
