(Actually, even further > upstream than that if my ISP was accommodating.) You are attempting to use a BROADCAST network (Ethernet) to solve a point-to-point networking problem. THIS WILL NOT WORK. Your problem has NOTHING to do with IP. Your problem is entirely rooted in your fundamental misunderstanding of what is and isn't possible to do with ETHERNET networks. > All (?)

It is trivial to use point-to-point networking technology to allow people to publish small groups of IP addresses and keep their private networks entirely separate from the Internet as a whole. That is NOT what you are attempting to do. You apparantly feel that you should be able to pervert a BROADCAST network into acting like a POINT-TO-POINT network. If you want point-to-point, invest in the appropriate technology. Since you have chosen to invest in broadcast networking hardware, you must live within the limitations imposed by the physical networking architecture. Your problems have nothing whatsoever to do with Internet standards and everything to do with your inability to separate physical layer protocols from network layer protocols. /Joe To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
