Lukier than I, using divert sockets + BRIDGE panics my machine. :) That sort of slowdown is pretty bad, however I'm quite sure it's possibile to only turn on bridging on select interfaces, why don't you try "sysctl -a" and look at the options given to you around "bridge"? One of the reasons the mcahine may be hosing out is because you somehow made a circular bridge and packets may circulate, try running tcpdump to make sure it's not happening. What does the system's "netstat -w 1" and "top" output show for system CPU usage? -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
