I experienced such a problem using bridging with two cards in my server. Someone showed me logs in which both Mac-Adresses of my cards were logged on one IP. The time in the logs and my hangtime are the same. Now i'm running without bridging (using a hub) and it works pretty fine now. I'm am running a FreeBSD 3.3-SNAPSHOT. Perhaps that helps. I'm a newby and can not really help you. So sorry, if a said something wrong. > > I don't see anything in the logs indicating what might have happened. > > Not only that, but ipfw *refuses* to log to syslog on this box!?!
