You're right ng_onetomany uses all the interfaces unless one goes down which is not what you're talking about. FreeBSD does not provide this functionality by default, but there are many hardware vendors that do provide cards that offer interface redundancy w/o the need for special software interfaces. That being said, you could write something, even in shell script, to poll an interface, and when it's state changes to down, or the link is no longer active, bring up and configure a new interface. This would lose all the existing connections, but new connections would survive the failover. --- Mark atkin901 at NOSPAM yahoo dot com (!wired)?(coffee++):(wired);
