Change the netmask of the alias from 255.255.255.0 to 255.255.255.255. I know it doesn't seem right, but all the FreeBSD machines I've worked on require aliases to have 255.255.255.255 as their netmask. -- Matthew Emmerton GSI Computer Services +1 (800) 217-5409 (Canada) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
