Doing it that way will do ALL interfaces, including loopback, which can break running programs that are using it. You can name one or more interfaces to be restarted instead of letting it do all of them. Do you have any reason to think the short leases time will somehow lead to changing IPs? My provider gives me 12 hour leases, and my IP hasn't changed in like 7 years. -- Ian
