BUT ONLY FreeBSD nodes do not work properly with the problem. All other system work normally I repeat: 2-3 connections to the FreeBSD node break down in every 10 minutes (in one node, we have 2 servers running FreeBSD). So if students were evil enough and did know my room number I could get one visitor after 3-5 minutes complaining about connections breaking down unexpectedly. I think every arp overwrite is breaking one connection down (I am not 100% sure of this, I have traced only few of them). Seppo
