It sounded more like a cable-modem-company inflicted problem anyway. I'm on Road Runner at home and they screw with my IP all the time. Similar symptoms. One thing that's different between us, though, is that they assign me a dynamic IP via DHCP not a static one. Is DHCP used in your system anywhere? > Two questions. > > 1.

If not, its probably not a FreeBSD problem. You also might want to try using ipfw to log traffic coming into your ethernet card in order to see if anything funny is going on. To do that, compile the pseudo device bpf and the options that have "IPFIREWALL" or "IPFILTER" in them into your kernel. Then set up some ipfw rules to log the data on your ethernet card. By doing this I've found a number of attempts by script kiddies to use Window vulnerabilities against my system. :) Jaime To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
