One solution could be the NetFPGA board which is rather decently
priced if you happen to be an academic customer. Although the FPGA
used (Virtex-II Pro 50) is somewhat old now.

Hi FPGA Gurus,
 I need to get a Gigabit Ethernet message, change its destination
IP,change some bits in the message(process) and send it out. I figure
out that I need 2 GigE ports to do that. I don't want to pay for the
MAC, so the board should be built with the Virtex 5 FPGAs or Altera
alternatives.
 Does a board like this exists?

You might post to comp.dcom.lans.ethernet and see what they
say over there.  I believe you need at least the PHY as
external.  The echo cancelation needed for gigabit is
pretty complicated.

I think a good solution would be to use a venerable Cyclone II Kit :
http://www.altera.com/products/devkits/altera/kit-nios-2c35.html
and plug two Gigabit Adapters in the SantaCruz connectors.

Can be developped using the free Quartus II Web edition.
We have all these items in stock if it can help, let me know.
The whole system can be up & running in just a few hours.
(we also have optimized GbE MAC etc)

Sorry for the silly question : do you absolutely need the two
/independent/ adapters ? GbE is bi-directional and a swicth will route 
and dispatch the flows. (You can receive a flow and re-send it at full 
speed with one single adapter)

You don't want to pay for a GbE MAC, so instead you want a Virtex 5?

I don't want to pay for a flight to Los Angeles, so instead I'm going
to buy my own jet and go to flight school.

Hello,
Yes, this dual GigE board exists at Sundance. Have a look at the
SMT945 from Sundance Multiprocessor Technology? It features a dual
Gigabit Ethernet ports (i.e. 2 GigE ports) and you can use it with the
SMT900 EVM that has a Virtex-5. You would then be able to implement
your logic in the Virtex-5 FPGA.
