Hi, for sniffing purposes I have a FreeBSD 4.9-STABLE box running on highend, state-of-the-art hardware (Xeon something) with all bells and whistles. The NIC´s an onboard copper em0 with gig-e capabilities. Nevertheless I am getting massive packet drops (40%-60%) when I start sniffing a gigabit

Christian, I recall reading some problems like this on this list recently. I don't remember if there was a solution for NATd, but running IPNAT compiled into the kernel has been highly efficient for my small office. I have no problems with transfers up to 3MB/sec. Maybe higher. I have also foun
