Why not just add an IP alias for the "new" network on each machine? Each system will respond to packets directed to either network, but without the complexity of a NAT box in the middle. Once you've got everything switched, then you can remove the original IP addresses. I've used this method in the past to transition LANs between IP ranges and it works absolutely fine. -- Matt Emmerton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
