Hi, I have a very strange problem, which I've now spent the last week trying to fix. The problem is that I loose the connection to my FreeBSD-box, which is acting as a bridge and has three NIC's (xl0, xl1 and fxp0). When I loose the connection, all traffic stops, ie. ssh, Samba, SMTP etc. The funny thing is that there are no problems with all other traffic, ie. all traffic for other hosts than the box is brdiged and works flawlessly. When the problem occurs (randomly, with no pattern) I can temporarily restore the connnection by clearing the ARP-table on my workstation (Windows 2000). However, I don't feel that having to clear the ARP-table every minute is the best solution, so I'm hoping that anyone can help me. :) I suspect it to be a bug in the kernel's bridging software. Until last friday I was running on a 4.2-STABLE (dated around February 1st), but after I cvsup'ed the sources the problem started to occur. Since then I've updated my sources daily (and thus running 4.3-BETA now), but so far with no luck. :( Besides bridging, I'm also using dummynet and ipfw in the kernel (for transparent firewall'ing/traffic shaping). I've tried to compile the kernel only with the bridging option added (based on the GENERIC file), but this didn't resolve the problem either. I've considered trying with some new NIC's, but I don't want to spend the money, if it doesn't help. If anyone have a solution to this, please don't hesitate to speak up. :) Best regards, Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
