I want to create Firewall with FPGA . I think I should use Virtex5 or better but I don't know how can I use fpga interface to NIC. It have no any example. What I have  to start to learn about FPGA and Firewall?

What sort of firewall? You can interface an FPGA with an Ethernet PHY - many development boards do this. If you don't know much about FPGAs or electronics at the moment, you should try to find a development board with at least two PHYs for a firewall application. At its simplest level you could implement an Ethernet bridge that passes all data from one interface to the other and vice versa. You could then examine the headers of packets and block them based on your criteria. A routing firewall will require you to rewrite packets slightly. Anything is possible beyond that, though there's a reason these sorts of things are usually done using processors.

I would start with the TEMAC product page below and go from there:
