Hi Pyun! I'll have to pop in a Copper Intel card that we have laying around in the lab. I think it's em(4) compatible.. I forget... I have a few things to test network wise this weekend, so I'll try and repro a few things this weekend (say, Sunday?). I also have my msk(4) enabled machine in the lab I can test with, but I'll have to install the machine to spec with the Poweredge 2950 I have in the lab. I'm using ipfw because it was easy to setup according to the handbook, but in reality if ipfw is this bad dealing with nat rules, then I need to work with someone to improve how it scales. Thanks! -Garrett _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
