Abstract :
Filtering of unauthorized packets is a common way to improve network security. Packet filtering is described as one of the firewall systems, which is generally implemented in gateways and routers. Packet filtering of gateways and routers is dangerous because an attacker may find the machine by its IP address. To resolve this security problem, we designed a packet filtering system without IP address. Using a personal computer and Linux as our system platform, we revise the operating system kernel to add filtering packet capability. Finally we implemented a secure packet filtering firewall and used it to protect our internal network from attack
