This is really odd, because I don't see this on my machines (as per our
discussion on IRC which you mention below), I did..

I also tried with a netmask of 255.255.255.255 - same result.
my sysctl.conf contains..
net.inet.ip.fw.one_pass=0
hw.intr_storm_threshold=15000
hw.snd.maxautovchans=4
hw.snd.pcm0.vchans=4
My kernel config is pretty standard - I've attached it if you want to look
through it.
I also tried it on a 6.0 amd64 machine -
FreeBSD eureka.gsoft.com.au 6.0-RC1 FreeBSD 6.0-RC1 #0: Wed Oct 26 13:29:47 UTC
2005 [EMAIL PROTECTED]:/usr/obj/local0/src/sys/GENESIS amd64
Same result..
