I don't actually use the machine for a firewall; perhaps that's why ipfw is having trouble, but it seems wrong for it to cause a panic :-). Machine is a 1.6GHz Pentium 4, 512M memory. Anyone seen this before? Is it fixed in more recent releases? I'll be upgrading to 4.7 soonish. jim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
