Most corporations are seriously concerned about security of their networks. Hence in order to secure their network from outside intruders they install firewalls which will be frontier defense against attacks from outside networks. But present system will use firewalls that cost high and are not fully flexible (manageable with changing environment).This paper suggests implementation of firewalls which will be built upon open source Linux operating system. We leverage flexibility of netfilter framework towards various networking operations and make use of IP-tables that will allow system administrators to configure tables which contain a set of chains which are ordered and set of rules. We used ns3 simulator to showcase proposed system. By using ns3 code we designed and simulated different modules of system and we gave explanation for each module. Finally we concluded our work and gave small description about future work © Research India Publications
