Introducing firewalls to IPv6. The first line of defense of most enterprise networks is a firewall that aims to prevent attacks from the public Internet to the enterprise network, and limits how local users can access the public Internet. As IPv6 is rolled out on enterprise networks, IPv6 firewalls will be deployed so that the same security policies that are currently being enforced in IPv4 are enforced in IPv6. I have several systems regularly being notified that application svhost was blocked and always blocked by the IPv6 firewall rule. All clients reporting this so far are Win7 units but I have not verified every instance either. The message everyone gets comes from 3 IPv6 sources on the network.

problem we 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 Rule based. Rule based systems are more advanced and cleverly built systems. A knowledge base programmed as rules will decide the output alongside an inference engine. If the defined rules for example all match, a certain assumption can be determined in which an action may take place. This assumption is the power of the inference engine.
