Due to exhaustion problem of IPv4 addresses the authors will soon switch over IPv6. To solve this problem they are presenting a Framework of a firewall for IPv6 and IPv4 networks using a Field-Programmable Gate Array (FPGA). The FPGA implements, the accept or deny rules of the firewall in Hardware using Verilog Hardware Description Language. A hardware based firewall offers the advantages of speed over a software firewall, in addition to direct interfacing with network devices, such as an Ethernet.
