I've also found the same setting in a couple of list groups. Here's what I have, but it doesn't seem to work: [root@localhost etc]# cat /etc/modprobe.conf options ip_conntrack hashsize=1048576 alias eth0 eepro100 ... I'm going to play around with it for a while. If I can't get it to work through modprobe I'll just tweak /etc/init.d/iptables to populate /sys/... since that seemed to work. I was just looking for a more elegant solution. Thanks for all of the help. This solve my problem of hitting the limits in any event. Gary
