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.

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.

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 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.

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?
