For 4.6 kernel it also required some patching. What version are you running?

Also the freebsd has to be an invisible hop on the network, so it can not route this traffic. I had setup my freebsd in bridge mode but I could not get this setup to work. You may need to increase your mtu to allow the full sized packets to pass through... or you could setup a vlan w/ and id that isn't used and let that adjust the mtu for you.. --=20 John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not." _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org"
