It should be fairly easy to write a netgraph module to do this. I suspect it will be very hard to forward a fully gigabit link worth of packets in this manner unless they are all fairly large and you have very good hardware, but you certaintly should be able to produce signifcant results. You're best bet is probably 5-CURRENT on a high performance SMP system with 3 PCI-X busses. An Opteron system will probably have the best performance. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
