【Abstract】 For improving firewall’function base on Linux, this paper, based on the linux 2.4 kernel netfilter, adopts packet filters fir ewall rules of iptables and function of modules kept in patch - o - matic (POM) repository, introduces simplified configuration rules and extended function of firewalls, and gives out simulative applications. The conclusion shows that efficiency of firewall is improved, functions of firewall are extended, and maintenance of the rules files becomes easier.更多还原
