Again, you are using a multipoint network in an inappropriate manner. Fundamentally, Ethernet is not point-to-point. Attempting to use it in a point-to-point manner, no matter whether or not you "think" that it should theoretically should be usable in such a manner, is irrelevant. Physically, it is not a point-to-point network. If you want point-to-point, set up X.25 links between the various points and run your network that way (aka, "ATM"). The physical network (Ethernet, aka, 802.*) is set up as a multipoint, broadcast network. Trying to pervert it into something else through misuse of software is not going to change the nature of the network. This is not a "usability" issue, it is an issue of your misunderstanding of networking design. I suggest that you attempt to explain the rationale behind your current network design to everyone once again and maybe we can all help you to a better understanding of how to accomplish your goals. /Joe To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
