基于IPv4／IPv6的SOCKS协议防火墙

在SOCKS客户机／服务器体系基础上，扩展了SOCKS服务器对IPv6的兼容功Ⅰ能，图示了基于IPv4/IPv6的SOCKSv5协议防火墙体系架构，重点论述了实现两种IPv4/IPv6地址转换模式的机制、原理，详细阐述了SOCKS客户机安全、透明地访问不同IP类地址远程主机的过程与原理，在现有SOCKS防火墙基础上，开发了IPv4/IPv6基于直接地址转换和域名解析地址转换两种模式的兼容运动技术，保持了SOCKSv5防火墙原有的优点，体现了其新的运行特点，使得这一新型防火墙技术具有更广泛的应用前景。

Study of SOCKS Firewall Based on IPv4/IPv6

An extended function of SOCKS firewall that enables smooth heterogeneous communications between the IPv4 nodes and IPv6 nodes based on the SOCKSv5 protocol is introduced, the architecture of translating IPv4 and IPv6 by applying the SOCKSv5 protocol is presented, there are two models of translating IPv4/IPv6 techniques and its mechanism, principle are more illustrated in details, an example for a SOCKS client securely transparent accessing to remote destination computer with different IP addresses is discussed. As well as the techniques of Direct Address Translation and DNS Name Resolving Delegation are developed , which it keeps the old SOCKSv5 firewalls' advantages, and shows another new characteristics. Therefore, the new firewalls technology are presented much wider application fields.
